Lucas De Marchi b0ac4ef074 drm/xe/guc_pc: Use poll_timeout_us() for waiting

Convert wait_for_pc_state() and wait_for_act_freq_limit() to
poll_timeout_us(). This brings 2 changes in behavior: Drop the
exponential wait and fix a potential much longer sleep.

usleep_range() will wait anywhere between `wait` and `wait << 1`, so
it's not correct to assume `slept += wait`.  This code is not really
accurate. Pairing this with the exponential wait increase, it could be
waiting much longer than intended.
