Cortex-X2 erratum 2017096 is a Cat B erratum that applies to
revisions r0p0, r1p0 & r2p0. The workaround is to set CPUECLTR_EL1[8]
to 1 which disables store issue prefetching.

This patch adds the basic CPU library code to support the Poseidon CPU
in TF-A. Poseidon is derived from HunterELP core, an implementation of
v9.2 architecture. Currently, Hunter CPU the predecessor to HunterELP,
is supported in TF-A. Accordingly the Hunter CPU library code has been
as the base and adapted here.

Cortex X2 erratum 2058056 is a Cat B erratum present in the X2 core.
It applies to revisions r0p0, r1p0, and r2p0 and is still open.
There are 2 ways this workaround can be accomplished, the first of
which involves executing a few additional instructions around MSR
writes to CPUECTLR when disabling the prefetcher. (see SDEN for
details)
However, this patch implements the 2nd possible workaround which sets
the prefetcher into its most conservative mode, since this workaround
is generic.
