drm/i915/dsi: Use TRANS_DDI_FUNC_CTL's own port width macro
[ Upstream commit 879f70382ff3e92fc854589ada3453e3f5f5b601 ]
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.
Cc: <stable@vger.kernel.org> # v6.5+
Fixes: b66a8abaa48a ("drm/i915/display/mtl: Fill port width in DDI_BUF_/TRANS_DDI_FUNC_/PORT_BUF_CTL for HDMI")
