Use the IS_ENABLED() macro to reduce amount of #ifdef use in the driver
and improve code coverage. With IS_ENABLED() macro, the code is compiled
and then optimized out, which prevents bitrot.
In case no PFC table matches the SoC in use, do not probe the driver
and instead exit with -ENODEV. This should never happen under normal
conditions, because this would mean the driver DT compatible string
match happened, but the list in probe() cannot match the model listed
in match data associated with the compatible string on which the match
did happen.

On the RZ/G2L SoC family, the direction of the Ethernet TXC/TX_CLK
signal is selectable to support an Ethernet PHY operating in either MII
or RGMII mode. By default, the signal is configured as an input and MII
mode is supported. The ETH_MODE register can be modified to configure
this signal as an output to support RGMII mode.
As this signal is be default an input, and can optionally be switched to
an output, it maps neatly onto an `output-enable` property in the device
tree.

The Ethenet interfaces on the Renesas RZ/G2L SoC family can operate at
multiple power supply voltages: 3.3V (default value), 2.5V and 1.8V.
rzg2l_pinconf_set() is extended to support the 2.5V setting, with a
check to ensure this is only used on Ethernet interfaces as it is not
supported on the SD & QSPI interfaces.
While we're modifying rzg2l_pinconf_set(), drop the unnecessary default
value for pwr_reg as it is set in every branch of the following if

This driver adds support for the gpio features of the GPIO/PFC module in
the Renesas RZ/G2L (R9A07G044) SoC.
The new `rzg2l-pfc-gpio` driver is bound to the same device tree node as
the `rzg2l-pfc-pinctrl` driver as the same hardware block provides both
GPIO and pin multiplexing features.

This driver adds support for the pinctrl features of the GPIO/PFC module
in the Renesas RZ/G2L (R9A07G044) SoC.
A multi-function `rzg2l-pfc` driver is defined for UCLASS_NOP, which
binds the `rzg2l-pfc-pinctrl` UCLASS_PINCTRL driver dynamically. We also
define common macros and functions for the PFC in <renesas/rzg2l-pfc.h>.
This makes it easy to add an additional UCLASS_GPIO driver for the GPIO
functionality of this module in a follow-up patch.

Currently, the Renesas pin control driver supports pins that can switch
their I/O voltage levels between either 1.8V and 3.3V, or between 2.5V
and 3.3V. However, some SoCs have pins that can switch between 1.8V and
2.5V.
Add support for this by replacing the separate SH_PFC_PIN_CFG_IO_VOLTAGE
capability and voltage level flags by a 2-bit field, to cover three
possible I/O voltage switching options.
