feat(arm): enable FHI PPI interrupt to report CPU errors
To handle the core corrected errors in the firmware, the FHI PPI
interrupt has to be enabled on all the cores. At boot, when the RAS
framework is initialized, only primary core is up and hence core FHI PPI
interrupt is enabled only on primary core. This patch adds support to
configure and enable core FHI interrupt for all the secondary cores as
part of their boot sequence.
