The VIN_DATA_PIN_GROUP() macro and vin_data{12,16,} unions are used to
define multiple VIN data groups with different numbers of lanes, while
referring to a single array of data pins, thus saving memory.
However, the same feature would be useful for other resizable buses,
like MMC, SDHI, QSPI, LCD, BSC, ...
Rework the mechanism for generic use:
- Use the new SH_PFC_PIN_GROUP_SUBSET() helper to remove the need for
bus-specific unions,
- Rename VIN_DATA_PIN_GROUP() to BUS_DATA_PIN_GROUP(),
- Rename the macro parameters to better reflect their purposes,
- Move the macro up, where it belongs.
Update all individual pin control drivers for the above changes.

It is fairly common for the pins in a pin group to be a subset of the
pins in another pin group. Add a macro for defining a pin group that
refers to a subset of an array of pins. This allows pin groups to share
pin data, and thus save memory.

Some instances of struct sh_pfc_soc_operations are called
"<soc>_pfc_ops", others are called "<soc>_pinmux_ops" or just
"pinmux_ops". Settle on the first variant, to avoid confusion with
"struct pinmux_ops" in the pinctrl core, and to increase consistency.

The second video-in channel on RZ/G1C has only 12 data lanes, but the
pin control driver uses the vin_data union, which is meant for 24 data
lanes, thus wasting space.
Fix this by using the vin_data12 union instead.
This reduces kernel size by 96 bytes.

This driver, like several others, uses a chained IRQ for each GPIO bank,
and forwards .irq_set_wake to the GPIO bank's upstream IRQ. As a result,
a call to irq_set_irq_wake() needs to lock both the upstream and
downstream irq_desc's. Lockdep considers this to be a possible deadlock
when the irq_desc's share lockdep classes, which they do by default:

However, this can never deadlock because the upstream and downstream
IRQs are never the same (nor do they even involve the same irqchip).
Silence this erroneous lockdep splat by applying what appears to be the
usual fix of moving the GPIO IRQs to separate lockdep classes.

Samsung pinctrl drivers changes for v5.18
1. Fix OF reference leak in pinctrl driver probe error path.
2. Correct list of handlers for Exynos850 ALIVE and CMGP pin banks.
3. Accept devicetrees with GPIO pin bank definitions named with a
"-gpio-bank" suffix. This is necessary for later Samsung pinctrl
