[U-Boot] [PATCH v3 0/9] Add pinmux command

[Patrice Chotard]

For debug purpose, it's useful to know the pins muxing
to check if a pin is configured as a GPIO or as an alternate
function and to get information about this alternate function
configuration. For this purpose a new command pinmux is implemented.

This series adds:
  - Add get_pin_muxing ops to UCLASS pinctrl
  - Add pinmux command
  - Add get_function() support to stm32 gpio driver
  - Add get_pins_count() support to stm32 pinctrl driver
  - Add get_pin_name() support to stm32 pinctrl driver
  - Add get_pin_muxing() support to stm32 pinctrl driver

Changes in v3:
 - Replace const char **buf parameter by char *buf, int size parameters
   for pinctrl_get_pin_muxing()
 - Replace const char **buf parameter by char *buf, int size parameters
   for pinctrl_get_pin_name()
 - Update calls to pinctrl_get_pin_name() and pinctrl_get_pin_muxing
   due to prototype update.
 - Fix typo

Changes in v2:
 - Replace pinmux_show ops which displayed the complete pin-controller
   muxing by get_pin_muxing ops which displays the muxing of one pin
 - In order to make pin muxing display less SoC specific,
   use pinctrl_pins_count(), pinctrl_get_pin_name() and
   pinctrl_get_pin_muxing() methods instead of
   previous pinctrl_pinmux_show() method.
