The local static 'struct pinctrl_desc' is not modified, so can be made
const for code safety.

Add support for generic pin parameter 'power-source'.
To maintain the backward compatibility, 'io-standard' parameter is still
supported in the driver.

Better to have a MODE group of settings to keep them together
when ordered alphabetically. Hence, rename PIN_CONFIG_LOW_POWER_MODE
to PIN_CONFIG_MODE_LOW_POWER.

It is expected that pinctrl drivers can extend pin_config_param because
of the gap between PIN_CONFIG_END and PIN_CONFIG_MAX so this conversion
isn't an issue. Most drivers that take advantage of this define the
PIN_CONFIG variables as constants, rather than enumerated values. Do the
same thing here so that Clang no longer warns.
