output-impedance-ohms
RZ/G2L supports two groups of pins Group-A and Group-B. For Group-A
pins drive-strength can be configured and for Group-B output-impedance
can be configured.
This patch splits PIN_CFG_IOLH macro to PIN_CFG_IOLH_A/B and adds
support to get/set drive-strength and output-impedance-ohms for the
supported pins.

Rename the below macros to match the HW manual (Rev.1.00):
PIN_CFG_IOLH_SD0 -> PIN_CFG_IO_VMC_SD0
PIN_CFG_IOLH_SD1 -> PIN_CFG_IO_VMC_SD1
PIN_CFG_IOLH_QSPI -> PIN_CFG_IO_VMC_QSPI
PIN_CFG_IOLH_ETH0 -> PIN_CFG_IO_VMC_ETH0
PIN_CFG_IOLH_ETH1 -> PIN_CFG_IO_VMC_ETH1

Add helper functions to read/read modify write pin config.
Switch to use helper functions for pins supporting PIN_CONFIG_INPUT_ENABLE
capabilities.

Rename RZG2L_SINGLE_PIN_GET_PORT -> RZG2L_SINGLE_PIN_GET_PORT_OFFSET.
Also, rename port -> port_offset in rzg2l_pinctrl_pinconf_set/get for
readability.
