In rzg2l_pinconf_set(), there are no new variables defined in the case
statement for PIN_CONFIG_INPUT_ENABLE so no additional scope is needed.

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
condition.

A later commit will make use of the pinctrl driver in TPL so let's add
the ability to build the Rockchip pinctrl driver in TPL.

unsigned int count is used to capture return of dev_read_string_count.
When an error occurs dev_read_string_count returns -ve, which can
hence not be handled correctly. Use int instead of unsigned int so
that errors are detected.
