drm/i915/cx0: Only clear/set the Pipe Reset bit of the PHY Lanes Owned
Currently, with MFD/pin assignment D, the driver clears the pipe reset bit
of lane 1 which is not owned by display. This causes the display
to block S0iX.
By not clearing this bit for lane 1 and keeping whatever default, S0ix
started to work. This is already what the driver does at the end
of the phy lane reset sequence (Step#8)
Bspec: 65451
Fixes: 619a06dba6fa ("drm/i915/mtl: Reset only one lane in case of MFD")
