This patch updates the wake mask and wake time to indicate to the
mce/mts that the cpu is powering down. Wake time is set to highest
possible value and wake mask is set to zero.

T194 XUSB has support for XUSB virtualization. It will have one
physical function (PF) and four Virtual function (VF)

There were below two SIDs for XUSB until T186.
1) #define TEGRA_SID_XUSB_HOST    0x1bU
2) #define TEGRA_SID_XUSB_DEV    0x1cU

We have below four new SIDs added for VF(s)
3) #define TEGRA_SID_XUSB_VF0    0x5dU
4) #define TEGRA_SID_XUSB_VF1    0x5eU
5) #define TEGRA_SID_XUSB_VF2    0x5fU
6) #define TEGRA_SID_XUSB_VF3    0x60U

When virtualization is enabled then we have to disable SID override
and program above SIDs in below newly added SID registers in XUSB
PADCTL MMIO space. These registers are TZ protected and so need to
be done in ATF.
a) #define XUSB_PADCTL_HOST_AXI_STREAMID_PF_0 (0x136cU)
b) #define XUSB_PADCTL_DEV_AXI_STREAMID_PF_0  (0x139cU)
c) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_0 (0x1370U)
d) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_1 (0x1374U)
e) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_2 (0x1378U)
f) #define XUSB_PADCTL_HOST_AXI_STREAMID_VF_3 (0x137cU)

This change disables SID override and programs XUSB SIDs in
above registers to support both virtualization and non-virtualization.

Fake system suspend for Tegra194, calls the routine
tegra_secure_entrypoint() instead of calling WFI.
In essence, this is a debug mode that ensures
that the code path of kernel->ATF and back to kernel
is executed without depending on other components
involved in the system suspend path.

This is for ensuring that verification of system suspend
can be done on pre-silicon platforms without depending on
the rest of the layers being enabled.

CPU0 is default on, so it doesn't need to run pwr_domain_on() at
boot. CPU0 AARCH64 will be set in pwr_domain_suspend(), but it may
encounter race condition with other CPUs.

Now AARCH64 will be set with cluster on in pwr_domain_on(), and
all CPUs on this cluster will be set together. It doesn't need to
set AARCH64 again in pwr_domain_suspend(), so the race condition
can be avoided.

ROMLIB extract functions code from BL images to put them inside ROM.
This has for effect to reduce the size of the BL images.

This patch take this size reduction into consideration to optimize the
memory layout of BL2.
A new "PLAT_ARM_BL2_ROMLIB_OPTIMIZATION" macro is defined and used to
reduce "PLAT_ARM_MAX_BL2_SIZE". This allows to remove the gap between
BL1 and BL2 when ROMLIB is used and provides more room for BL31.

The current memory gain is 0x6000 for fvp and 0x8000 for juno.

N1SDP supports multichip configuration wherein n1sdp boards are

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

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.

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.
