pinctrl: renesas: r8a7778: Use common R-Car bias handling

Browse source

Currently, the rcar_pinmux_[gs]et_bias() helpers handle only SoCs that
have separate LSI Pin Pull-Enable (PUEN) and Pull-Up/Down Control (PUD)
registers, like R-Car Gen3 and RZ/G2.  Update the function to handle
SoCs that have only LSI Pin Pull-Up Control Register (PUPR), like R-Car
Gen1/Gen2 and RZ/G1.

Reduce code duplication by converting the R-Car M1A pin control driver
to use the common handler.

Note that this changes behavior in case the (invalid!) option
"bias-pull-down" is used in an R-Car M1A DTS: before, it was ignored
silently; after this change, it is considered the same as
"bias-pull-up".
