drm/i915: Only poll DW3_A when init DDI PHY for ports B and C.
According to Bspec we need to
"Poll for PORT_REF_DW3_A grc_done == 1b"
only on ports B and C initialization sequence when
copying rcomp from port A.
So let's follow the spec and only poll for that case
and not on every port A initialization.
v2: Also remove the grc_done check from bxt_ddi_phy_is_enabled()
otherwise it might believe it is disabled and force it to re program.
