rcar_gen3: plat: Prevent PCIe hang during L1X config access
In case the PCIe controller receives a L1_Enter_PM DLLP, it will
disable the internal PLLs. The system software cannot predict it
and can attempt to perform device config space access across the
PCIe link while the controller is in this transitional state. If
such condition happens, the PCIe controller register access will
trigger ARM64 SError exception.
This patch adds checks for which PCIe controller is enabled,
checks whether the PCIe controller is in such a transitional
state and if so, first completes the transition and then restarts
the instruction which caused the SError.

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.

fvp: trusty: Move dynamic xlat enable to platform
Rather than letting the Trusty makefile set the option to enable dynamic
translation tables, make platforms do it themselves.
This also allows platforms to replace the implementation of the
translation tables library as long as they use the same function
prototypes.
