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.

Disable processor Cycle Counting in Secure state
In a system with ARMv8.5-PMU implemented:
- If EL3 is using AArch32, setting MDCR_EL3.SCCD to 1 disables counting
in Secure state in PMCCNTR.
- If EL3 is using AArch64, setting SDCR.SCCD to 1 disables counting in
Secure state in PMCCNTR_EL0.
So far this effect has been achieved by setting PMCR_EL0.DP (in AArch64)

as any EL can change that value.

Update macro to check need for CVE-2017-5715 mitigation
Armv8.5 introduces the field CSV2 to register ID_AA64PFR0_EL1. It can
have the following 3 values:
- 0: Branch targets trained in one hardware described context may affect
speculative execution in a different hardware described context. In
some CPUs it may be needed to apply mitigations.
- 1: Branch targets trained in one hardware described context can only
affect speculative execution in a different hardware described
context in a hard-to-determine way. No mitigation required.
- 2: Same as 1, but the device is also aware of SCXTNUM_ELx register
contexts. The TF doesn't use the registers, so there is no
difference with 1.
The field CSV2 was originally introduced in the TRM of the Cortex-A76
before the release of the Armv8.5 architecture. That TRM only mentions
the meaning of values 0 and 1. Because of this, the code only checks if
the field has value 1 to know whether to enable or disable the
mitigations.
This patch makes it aware of value 2 as well. Both values 1 and 2
disable the mitigation, and 0 enables it.
