pinctrl: actions: remove MODULE_LICENSE in non-modules

Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as
modules.

pinctrl: actions: pinctrl-s900: Constify s900_padinfo[]

The only usage of s900_padinfo[] is to assign it to the padinfo field in
the owl_pinctrl_soc_data struct, which is a const pointer. Make it const
to allow the compiler to put it in read-only memory.

pinctrl: actions: define pad control configurtion to SoC specific

pad control for s900 and s700 are differs in number of
pull control configuraions
s900 has 4 pull controls - high impedence, pull up, pull down, repeater
s700, s500 has 2 pull controls - pull up and pull down

so pad control configuration has to SoC specific, moved out from pinctrl
common to s900 specific.

pinctrl: actions: make s900_functions, s900_padinfo and s900_pads static

s900_functions, s900_padinfo and s900_pads are local to the source and do
not need to be in global scope, so make them static.

pinctrl: actions: Add Actions S900 pinctrl driver

Add pinctrl driver for Actions Semi S900 SoC. The driver supports
pinctrl, pinmux and pinconf functionalities through a range of registers
common to both gpio driver and pinctrl driver.

Pinmux functionality is available only for the pin groups while the
pinconf functionality is available for both pin groups and individual
pins.
