[PATCH v2 8/9] drm/xe/xe_ras: Move xe drm_ras registration

[Raag Jadav <raag.jadav@intel.com>]

From: Riana Tauro <riana.tauro@intel.com>

gove xe drm_ras registration to RAS initialization flow and keep
gardware error initialization for processing errors reported
via irq.

Also reorder soc remapper and system controller initialization to
early probe as ras init is dependent on both.
