drm/xe/guc: Refactor GuC load to use poll_timeout_us()

Browse source

Currently there are 2 wait loops for loading GuC: one in
xe_mmio_wait32_not() and one guc_wait_ucode(). Now that there's a
generic poll_timeout_us(), refactor the code to use that to be more
readable.

Main change in behavior is that there's no exponential wait anymore:
that is now replaced by a 10msec retry.
