The ARM_PLAT_MT bit enables the support for MT bit in
MPIDR format. This means that the level 0 affinity
represents the thread and CPU / Cluster levels are
at affinity level 1 and 2 respectively.
This was not catered for in the scpi 'css_scp_get_power_state, API.
Since the SCPI driver can only cater for single threaded CPUs,
this patch fixes the problem by catering for this shift by
effectively ignoring the Thread (level 0) affinity level.

 RK3399: Shrink M0 SRAM code to fit in PMUSRAM

The 'impl' variable is guarded by the symbol DEBUG, but used in an INFO
level print statement. INFO is defined based on LOG_LEVEL. Hence, builds
would fail when
 - DEBUG=0 && LOG_LEVEL>=LOG_LEVEL_INFO with a variable used but not defined
 - DEBUG=1 && LOG_LEVEL<LOG_LEVEL_INFO with a variable defined but not used

Fixing this by guarding impl with the same condition that guards INFO.

This moves the DRAM restore code to PMUSRAM. This is so that the

be turned off during system suspend.

This removes the mmio_... function calls to set the multicast bit for
the PHY registers when overriding the write leveling values. These are
not needed since multicast is set by default when calling the
function, and it's also better not to leave the side effect of
disabling multicast when exiting the function.

This removes the space allocation for the unused PHY register space.
For instance in PHY registers 0-127, only 0-90 are used, so don't save
the 91-127 registers. This saves about 1.6KB of space.

The differential signal of DQS need keep low level
before gate training. It need enable RPULL and disable
PHY side ODT to ensure it when do gate training.
But it can not access the PHY registers to do it when
perform DFS.So the workaroud as below: It is ensure that
the PHY's read gate is landing somewhere in the incoming
DQS's pulses before it starts searching for pre-amble window.
It need get the rddqs_delay_ps to calculate the start point
of gate training for DFS.

Update the path for firmware_image_package.h in firmware-design.md

If `MBEDTLS_PLATFORM_SNPRINTF_ALT` isn't used, the function
`mbedtls_platform_set_snprintf()` isn't defined.

In case a platform uses a different mbed TLS configuration file than
the one provided by the Trusted Firmware, and it doesn't define the
mentioned build option, this will result in a build error.

This patch modifies the initialization code so that
`mbedtls_platform_set_snprintf()` is only used if
`MBEDTLS_PLATFORM_SNPRINTF_ALT` is defined, allowing platforms to use
it or not depending on their needs.
