Arm's GIC-600 features a Power Register (GICR_PWRR),
which needs to be programmed to enable redistributor
operation. Section 3.6.1 in the GIC-600 TRM describes
the power-up and power-down sequence in pseudo code,
which deviates from the current TF-A implementation
in drivers/arm/gic/v3/gic600.c.
For powering on a redistributor, the pseudo code suggests
to loop over the whole sequence (check for transition,
write request bit) instead of just looping over the
ready bit read as TF-A does in gic600_pwr_on().
This patch fixes GIC-600 power up sequence according
to the TRM.

Previous implementation of timers assumed that clk_div has pretty
representation in MHz (10MHz, 100MHz, etc). Unusual frequencies
(99.99MHz) were causing assertion error and made udelay unusable.

`unsigned long` should be replaced to
1. `unsigned int` or `unsigned long long` - If fixed,
based on the architecture AArch32 or AArch64
2. `u_register_t` - If it is supposed to be 32-bit
wide in AArch32 and 64-bit wide in AArch64.

Translation descriptors are always 32-bit wide, here
`uint32_t` is used to describe the `exact size` of
translation descriptors instead of `unsigned int` which
guarantees minimum 32-bits

* changes:
  gic/gic600: add support for multichip configuration
  plat/arm/gicv3: add support for probing multiple GIC Redistributor frames

N1SDP supports multichip configuration wherein n1sdp boards are
connected over high speed coherent CCIX link, for now only dual-chip
is supported.

Whether or not multiple chips are present is dynamically probed by
SCP firmware and passed on to TF-A, routing table will be set up
only if multiple chips are present.

Initialize GIC-600 multichip operation by overriding the default GICR
frames with array of GICR frames and setting the chip 0 as routing
table owner.

Add support to configure GIC-600's multichip routing table registers.
Introduce a new gic600 multichip structure in order to support platforms
to pass their GIC-600 multichip information such as routing table owner,
SPI blocks ownership.

This driver is currently experimental and the driver api may change in
the future.

Earlier PIE support was enabled for all arm platforms when
RESET_TO_BL31=1, but later on it was restricted only to FVP with patch
SHA d4580d17

 because of n1sdp platform.

Now it has been verified that PIE does work for n1sdp platform also, so
enabling it again for all arm platforms.

ARM platform can have a non-contiguous GICR frames. For instance, a
multi socket platform can have two or more GIC Redistributor frames
which are 4TB apart. Hence it is necessary for the `gicv3_rdistif_probe`
function to probe all the GICR frames available in the platform.

Introduce `plat_arm_override_gicr_frames` function which platforms can
use to override the default gicr_frames which holds the GICR base
address of the primary cpu.

* changes:
  n1sdp: update platform macros for dual-chip setup
  n1sdp: introduce platform information SDS region

N1SDP supports multichip configuration wherein n1sdp boards are
connected over high speed coherent CCIX link  for now only dual-chip is
supported.

A single instance of TF-A runs on master chip which should be aware of
slave chip's CPU and memory topology.

This patch updates platform macros to include remote chip's information
and also ensures that a single version of firmware works for both single
and dual-chip setup.

Platform information structure holds information about platform's DDR
size(local/remote) which will be used to zero out the memory before
enabling the ECC capability as well as information about multichip
setup. Multichip and remote DDR information can only be probed in SCP,
SDS region will be used by TF-A to get this information at boot up.

This patch introduces a new SDS to store platform information, which is
populated dynamically by SCP Firmware.previously used mem_info SDS is
also made part of this structure itself.

The platform information is also passed to BL33 by copying it to Non-
Secure SRAM.

Some of the plantuml diagrams in the I/O storage abstraction layer
documentation are absent from the rendered version of the porting
guide. The build log (see [1] for example) reports a syntax error in
these files. This is due to the usage of the 'order' keyword on the
participants list, which does not seem to be supported by the version
of plantuml installed on the ReadTheDocs server.

Fix these syntax errors by removing the 'order' keyword altogether. We
simply rely on the participants being declared in the desired order,
which will be the order of display, according to the plantuml
documentation.
