drm/i915/gsc: take a wakeref for the proxy-init-completion check
Ensure intel_gsc_uc_fw_init_done and intel_gsc_uc_fw_proxy_init
takes a wakeref before reading GSC Shim registers.
NOTE: another patch in review also adds a call from selftest to
this same function. (https://patchwork.freedesktop.org/series/117713/)
which is why i am adding the wakeref inside the callee, not the
caller.
v2: - add a helper, 'gsc_uc_get_fw_status' for both callers
(Daniele Ceraolo)
