Arm platforms: Remove common RAS configuration source ...

The file arm_ras.c intended to provide common platform-specific RAS
configuration for Arm platforms. Because this file has symbol
definitions, it's proving difficult to provide a common definition.

This patch therefore renames and makes the file specific to FVP. Other
platforms shall provide their own configuration in similar fashion.

My thanks to Daniel Thompson and Ard Biesheuvel for the bits and pieces
I've taken from their earlier work regarding build and deploy steps for
Developerbox based on Synquacer SoCs. They deserve much of the credit
for this work although, since I assembled and tested things, any blame
is probably mine.

BL31 runs from SRAM which is a non-coherent memory on synquacer. So
enable MMU with SRAM memory marked as Non-Cacheable and mark page tables
kept on SRAM as Non-Cacheable via XLAT_TABLE_NC flag. Also add page tables
for Device address space.

ARM Platforms: Update CNTFRQ register in CNTCTLBase frame ...

Currently TF-A doesn't initialise CNTFRQ register in CNTCTLBase
frame of the system timer. ARM ARM states that "The instance of
the register in the CNTCTLBase frame must be programmed with this
value as part of system initialization."

The psci_arch_setup() updates the CNTFRQ system register but
according to the ARM ARM, this instance of the register is
independent of the memory mapped instance. This is only an issue
for Normal world software which relies on the memory mapped
instance rather than the system register one.

This patch resolves the issue for ARM platforms.

The patch also solves a related issue on Juno, wherein
CNTBaseN.CNTFRQ can be written and does not reflect the value of
the register in CNTCTLBase frame. Hence this patch additionally
updates CNTFRQ register in the Non Secure frame of the CNTBaseN.

Fixes ARM-Software/tf-issues#593
