gpiolib: enable CONFIG_GPIOLIB_LEGACY even for !GPIOLIB

Browse source 
A few drivers that use the legacy GPIOLIB interfaces can be enabled
even when GPIOLIB is disabled entirely. With my previous patch this
now causes build failures like:

   drivers/nfc/s3fwrn5/uart.c: In function 's3fwrn82_uart_parse_dt':
        drivers/nfc/s3fwrn5/uart.c💯14: error: implicit declaration of function 'gpio_is_valid'; did you mean 'uuid_is_valid'? [-Werror=implicit-function-declaration]

These did not show up in my randconfig tests because randconfig almost
always has GPIOLIB selected by some other driver, and I did most
of the testing with follow-up patches that address the failures
properly.

Move the symbol outside of the 'if CONFIG_GPIOLIB' block for the moment
to avoid the build failures. It can be moved back and turned off by
default once all the driver specific changes are merged.
