The new ARMv8 SoC, PH1-LD20, supports more fine-grained drive
strength control. Some of the configuration registers on it have
3-bit width.
The feature will be supported in the next commit, but a problem is
that macro names are getting longer and longer in the current naming
scheme.
Before moving forward, this commit renames macros as follows:
UNIPHIER_PIN_DRV_4_8 -> UNIPHIER_PIN_DRV_1BIT
UNIPHIER_PIN_DRV_8_12_16_20 -> UNIPHIER_PIN_DRV_2BIT
UNIPHIER_PIN_DRV_FIXED_4 -> UNIPHIER_PIN_DRV_FIXED4
UNIPHIER_PIN_DRV_FIXED_5 -> UNIPHIER_PIN_DRV_FIXED5
UNIPHIER_PIN_DRV_FIXED_8 -> UNIPHIER_PIN_DRV_FIXED8

Currently, every SoC driver defines struct pinctrl_desc statically,
i.e. it consumes memory footprint even if it is not probed.
In multi-platform, many pinctrl drivers are linked (generally as
built-in objects), although only one of them is actually used.
So, it is reasonable to allocate memory dynamically where possible.

Every SoC driver sets the same name for struct pinctrl_desc and
platform_driver. The common probe function can set desc->name
instead of duplicating strings in each SoC driver.

The owner of the struct pinctrl_desc matches that of platform_driver.
Set it in the common probe function.

These pin tables were generated by parsing hardware documents with
a script, but the script had a bug. Fix the register offsets.

Make function/variable names match the file names for consistency.

Use devm_pinctrl_register() for pin control registration and remove
need of .remove callback.

The current "CONFIG_PINCTRL_UNIPHIER_PH1_*" is too long. It would
not hurt to drop "PH1_" because "UNIPHIER_" already well specifies
the SoC family. Also, rename files for consistency.
