pinctrl: Add new function pinctrl_generic_set_state_prefix()

Browse Source 
This new function pinctrl_generic_set_state_prefix() behaves like
pinctrl_generic_set_state() but it takes third string argument which is
used as the prefix for each device tree string property.

This is needed for Marvell pinctrl drivers, becase Linux device tree files
have pinmux properties prefixed by "marvell," string.

This change allows to use generic U-Boot pinctrl functions for Armada 38x
pinctrl driver without need to copy+paste of the majority U-Boot pinctrl
code.
