pinctrl: include linux/errno.h in consumer.h for ENOTSUPP

Browse Source 
The CONFIG_PINCTRL=n stubs of pinctrl_gpio_get_config() and
pinctrl_gpio_set_config() return -ENOTSUPP, but the header only pulls in
linux/err.h, which provides asm/errno.h and not the kernel-internal
ENOTSUPP from linux/errno.h. A translation unit that includes
pinctrl/consumer.h before anything else fails to build:

  include/linux/pinctrl/consumer.h:110:10: error: use of undeclared identifier 'ENOTSUPP'

Include linux/errno.h explicitly.

Fixes: b44aec8765 ("pinctrl: make the CONFIG_PINCTRL=n gpio config stubs return -ENOTSUPP")
