pinctrl: renesas: rzg2l: Unify power source handling

The previous code handled power sources using a mixture of power
source specific definitions and lookups in the available_ps[] array.
Unify the power source handling by introducing struct
rzg2l_pinctrl_ps_desc, whose purpose is to describe a power source
through its power source value, associated register value, associated
capabilities (e.g. Ethernet), and associated IOLH index.

Introduce two new functions, rzg2l_ps_to_desc() and
rzg2l_pwr_reg_val_to_desc(), using the
RZG2L_PINCTRL_PS_DESC_MEMBER_TO_DESC_FUNC() macro, as their
implementations are similar.

These functions retrieve a power source descriptor based on either a
power source value or a power source register value.  Other functions
that need to perform power source specific operations can call them to
retrieve the corresponding power source descriptor.

The register values for the soft power sources were kept to zero since
they are not used across the driver's code.
