extcon: palmas: Fix build break due to devm_gpiod_get_optional API change 

With commit b17d1bf16c ("gpio: make flags mandatory for gpiod_get functions")
it becomes necessary to pass the flags argument. And this patch adds the gpio
header file to fix the build breakage when build testing with random
configuration files.
