drm/i915/display: Use int for entry setup frames

Browse Source 
At least one TGL had regression when using u8 types
for entry setup frames calculation. So, let's switch
to use ints instead.

intel_psr_entry_setup_frames() function expects
to return u8 but since in case of error the error
code -ETIME is returned. This doesn't fit into u8
and hence the return value is not as expected.

Fixes: 2b981d57e4 ("drm/i915/display: Support PSR entry VSC packet to be transmitted one frame earlier")
