[PATCH] gpio: Use str_enable_disable-like helpers

[PATCH] gpio: Use str_enable_disable-like helpers

[Krzysztof Kozlowski]

Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read.  Ternary
   operator has three arguments and with wrapping might lead to quite
   long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary
   file.
