pinctrl: sh-pfc: r8a7795: Use lookup function for bias data 

There is a bug in the r8a7795 bias code where a WARN() is trigged
anytime a pin from PUEN0/PUD0 is accessed.

 # cat /sys/kernel/debug/pinctrl/e6060000.pfc/pinconf-pins

This is due to the WARN() check if the reg field of the pullups struct
is zero, and this should be 0 for pins controlled by the PUEN0/PUD0
registers since PU0 is defined as 0. Change the data structure and use
the generic sh_pfc_pin_to_bias_info() function to get the register
offset and bit information.
