pinctrl: renesas: rzg2l: Generalize power source code

The current functions used to get/set the pin power source check the
OTHER_POC register, which is specific to the RZ/G3L SoC only.  To allow
the code to be extended for other power source functionalities (e.g. I3C
on RZ/G3S), generalize the functions used to get/set the pin power
source.

For this, introduce the struct rzg2l_register_masks data structure whose
purpose is to store SoC specific register bit masks.  The members of
this structure are then used in rzg2l_caps_to_pwr_reg() to retrieve the
bitmask corresponding to a SoC specific power source capability.

The conversion between HW specific power source values and SW specific
power source values is now handled through rzg2l_pwr_reg_val_to_ps() and
rzg2l_ps_to_pwr_reg_val().

Finally, to keep the code generic, the register update in
rzg2l_set_power_source() was changed to a read-modify-write approach to
cover all cases.
