regmap: allow busses to request formatting with specific endianness

Add a field to struct regmap_bus that allows bus drivers to request that
register addresses and values be formatted with a specific endianness.

The default endianness is unchanged from current operation: Big.

Implement native endian formatting/parsing for 16- and 32-bit values.
This will be enough to support regmap-mmio.c.

regmap: mmio: request native endian formatting

This will avoid the regmap core converting all addresses and values into
big endian, only for the mmio bus driver to have to convert them back to
native endian.

regulator: core: Allow drivers to set voltage mapping table in regulator_desc

Some regulator hardware use table based mapping can set volt_table in
regulator_desc and use regulator_list_voltage_table() for their list_voltage
callback.

regulator: core: Call set_voltage_time_sel() only when the regulator is on

If the regulator is not on, it won't take time setting new voltage.
So only call set_voltage_time_sel() to get the necessary delay when
the regulator is on.

regulator: Use newly added devres_release() rather than open coding

devres_release() will call the destructor for the resource as well as
freeing the devres data.

regulator: core: Use dev_get_regmap() to find the regmap

If no regmap is explicitly specified then use dev_get_regmap() to obtain
one. The driver must explicitly enable any actual usage of the regmap
so there's no concern with unwanted usage.
