[Intel-gfx] [PATCH v2 3/6] drm/i915/uc: Create intel_uc_init_mmio

[Michal Wajdeczko]

From: Sagar Arun Kamble <sagar.a.kamble at intel.com>

This patch adds new function intel_uc_init_mmio which will initialize
MMIO access related variables prior to uc load/init.

v2: Removed unnecessary export of guc_send_init_regs. Created
intel_uc_init_mmio that currently wraps guc_init_send_regs. (Michal)
