bl1-smc-handler: Ensure the lower-order 16 bits of SPSR are programmed
A bug recently fixed in bl2/aarch32/bl2_el3_entrypoint.S relates to
programming the lower-order 16 bits of the SPSR to populate into the CPSR
on eret.
The BL1 smc-handler code is identical and has the same shortfall in
programming the SPSR from the platform defined struct
entry_point_info->spsr.
msr spsr, r1 will only update bits f->[31:24] and c->[7:0] respectively. In
order to ensure the 16 lower-order processor mode bits x->[15:8] and
c->[7:0] this patch changes msr spsr, r1 to msr spsr_xc, r1.
This change ensures we capture the x field, which we are interested in and
not the f field which we are not.

bl2-el3: Fix exit to bl32 by ensuring a more complete write to SPSR
Prior to entry into BL32 we set the SPSR by way of msr spsr, r1.
This unfortunately only writes the bits f->[31:24] and c->[7:0].
This patch updates the bl2 exit path to write the x->[15:8] and c->[7:0]
fields of the SPSR. For the purposes of initial setup of the SPSR the x and
c fields should be sufficient and importantly will capture the necessary
lower-order control bits that f:c alone do not.
This is important to do to ensure the SPSR is set to the mode the platform
intends prior to performing an eret.

imx: make sure GIC redistributor is awake before initialization
GICR_WAKER.ProcessorSleep can only be set to zero when:
— GICR_WAKER.Sleep bit[0] == 0.
— GICR_WAKER.Quiescent bit[31] == 0.
On some platforms, when system reboot with GIC in sleep
mode but with power ON, such as on NXP's i.MX8QM, Linux
kernel enters suspend but could be requested to reboot,
and GIC is in sleep mode and it is inside a power domain
which is ON in this scenario, when CPU reset, the GIC
driver trys to set CORE's redistributor interface to awake,
with GICR_WAKER.Sleep bit[0] and GICR_WAKER.Quiescent bit[31]
both set, the ProcessorSleep bit[1] will never be clear
and cause system hang.
This patch makes sure GICR_WAKER.Sleep bit[0] and
GICR_WAKER.Quiescent bit[31] are both zeor before clearing
ProcessorSleep bit[1].

Add ARMv8.3-PAuth registers to CPU context
ARMv8.3-PAuth adds functionality that supports address authentication of
the contents of a register before that register is used as the target of
an indirect branch, or as a load.
This feature is supported only in AArch64 state.
This feature is mandatory in ARMv8.3 implementations.
This feature adds several registers to EL1. A new option called
CTX_INCLUDE_PAUTH_REGS has been added to select if the TF needs to save
them during Non-secure <-> Secure world switches. This option must be
enabled if the hardware has the registers or the values will be leaked
during world switches.
To prevent leaks, this patch also disables pointer authentication in the
Secure world if CTX_INCLUDE_PAUTH_REGS is 0. Any attempt to use it will
be trapped in EL3.
