Hi Geert, Laurent

Gen2 / Gen3 next datasheet will has below note.
Our current PFC settings order is
	MOD_SEL -> GPSR -> IPSR
But, this fixes it to
	MOD_SEL -> IPSR -> GPSR

------------
IPSRx and MOD_SELx registers shall be set before setting GPSRx
registers in case that they need to be configured.
MOD_SELx registers can be set either earlier or later than setting
IPSRx registers.
------------

1) patch make it easy to check
2) patch fixes above

Kuninori Morimoto (2):
      1) pinctrl: sh-pfc: enable to indicate GPSR/IPSR/MOD_SEL for debug
      2) pinctrl: sh-pfc: IPSRx and MOD_SELx should be set before GPSRx
