For STM32MP1, the address space is 4GB, which can be first divided
in 4 parts of 1GB. This LVL1 table is already mapped regardless
of MAX_XLAT_TABLES.
Fixing typo: Replace Ko to KB.

BL2/sp_min for platform STM32MP1 requires 4 MMU translation tables:
  - a level2 table and a level3 table for identity mapped SYSRAM
  - a level2 table mapping 2MB of BootROM runtime resources
  - a level2 table mapping 2MB of secure DDR (case BL32 is OP-TEE)

NOTE for platform integrators:
   API `plat_psci_stat_get_residency()` third argument
   `last_cpu_idx` is changed from "signed int" to the
   "unsigned int" type.

Issue / Trouble points
1. cpu_idx is used as mix of `unsigned int` and `signed int` in code
with typecasting at some places leading to coverity issues.

2. Underlying platform API's return cpu_idx as `unsigned int`
and comparison is performed with platform specific defines
`PLAFORM_xxx` which is not consistent

Misra Rule 10.4:
The value of a complex expression of integer type may only be cast to
a type that is narrower and of the same signedness as the underlying
type of the expression.

Based on above points, cpu_idx is kept as `unsigned int` to match
the API's and low-level functions and platform defines are updated
where ever required

CLK_TOPSW_LSBUS is parent of WDT clock. Clock from invalid
clock list would not be registered to CCF framework and so
cannot be used as parent of other clocks.

WDT clock has default parent as CLK_TOPSW_LSBUS(APB clock).
If CLK_TOPSW_LSBUS is not registered, CCF would not recognize
that clock and hence rate of WDT clock would be calculated to
be 0 by CCF(as parent rate is considered 0).

So it is necessary to allow registration of CLK_TOPSW_LSBUS
clock.

GEM-related clock models were incorrect and are fixed as follows
(documented below for GEM0, but the same holds for any GEM ID):

- CLK_GEM0_REF_UNGATED represents clock that has DIV0/1 divisors and
 the multiplexer controllable in GEM0_REF_CTRL (CRL_APB). The ID of this
 clock is newly introduced in this patch.

- CLK_GEM0_REF models the clock mux that selects the reference clock
 for Tx, i.e. selects CLK_GEM0_REF_UNGATED or external Tx clock. This
 mux is controllable via GEM_CLK_CTRL (IOU_SLCR), bit GEM0_REF_SRC_SEL.
 Note that the routing of external clock to the mux is not modelled
 and is assumed to be configured by the FSBL if required, and not
 changeable at runtime. The ID of this clock is introduced in this patch.

- CLK_GEM0_TX models clock with only a gate that is controlled via
 bit 25 in GEM0_REF_CTRL (CRL_APB). The parent of this clock is
 CLK_GEM0_REF. The clock ID of CLK_GEM0_TX matches the previous ID
 value of CLK_GEM0_REF. This is done in order to fix the clock models
 and incorrect binding without requiring to change device-tree (binding
 of clock IDs to GEM interface).

- CLK_GEM0_RX models clock that has only gate controlled via RX_CLKACT
 bit (26) in GEM0_REF_CTRL (CRL_APB). Parent of this clock is sourced
 from external RGMII PHY (via MIO or EMIO). We do not model the whole
 clock path to the Rx gate, since this is configured by the FSBL and
 never changed at runtime (and there is no mechanism to change the
 path at runtime). The clock ID of CLK_GEM0_RX clock is equal to the
 previous ID value of CLK_GEM0_TX clock. This is done because the TX/RX
 were swapped in device tree, so by fixing the IDs this way there is no
 need for device tree fix.

Rates of the external RX/TX clocks can be specified in device tree if
needed. Right now, that's not necessary because Tx clock is sourced
from an on-chip PLL (via CLK_GEM0_REF_UNGATED/CLK_GEM0_REF), whereas
the Rx clock is sourced from external reference and the driver never
attempts to get/get clock rate (only to enable it). If this changes in
future, ATF clock model doesn't need to be changed. Instead, the clock
rates for gem0_tx_ext and gem0_rx_ext have to be specified in device
tree.

The SCU connects one to four Cortex-A5/Cortex-A9 processors
to the memory system through the AXI interfaces.

The SCU functions are to:
- maintain data cache coherency between the Cortex-A5/Cortex-A9
  processors
- initiate L2 AXI memory accesses
- arbitrate between Cortex-A5/Cortex-A9 processors requesting
  L2 accesses
- manage ACP accesses.

Snoop Control Unit will enable to snoop on other CPUs caches.
This is very important when it comes to synchronizing data between
CPUs. As an example, there is a high chance that data might be
cache'd and other CPUs can't see the change. In such cases,
if snoop control unit is enabled, data is synchoronized immediately
between CPUs and the changes are visible to other CPUs.

This driver provides functionality to enable SCU as well as enabling
user to know the following
- number of CPUs present
- is a particular CPU operating in SMP mode or AMP mode
- data cache size of a particular CPU
- does SCU has ACP port
- is L2CPRESENT
