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