drm/i915/icl: Fix setting 10 bit deep color mode

There is a bug in hdmi_deep_color_possible() - we compare pipe_bpp
<= 8*3 which returns true every time for hdmi_deep_color_possible 12 bit
deep color mode test in intel_hdmi_compute_config().(Even when the
requested color mode is 10 bit through max bpc property)

Comparing pipe_bpp with bpc * 3 takes care of this condition where
requested max bpc is 10 bit, so hdmi_deep_color_possible with 12 bit
returns false when requested max bpc is 10.(Ville)

v2:Add suggested by Ville Syrjälä
