drm/i915/dsi: Use TRANS_DDI_FUNC_CTL's own port width macro
The format of the port width field in the DDI_BUF_CTL and the
TRANS_DDI_FUNC_CTL registers are different starting with MTL, where the
x3 lane mode for HDMI FRL has a different encoding in the two registers.
To account for this use the TRANS_DDI_FUNC_CTL's own port width macro.
