regulator: rk808: add #include for gpiod functions
This fixes a build problem on mips found by the kbuild test robot:
drivers/regulator/rk808-regulator.c: In function 'rk808_buck1_2_get_voltage_sel_regmap':
drivers/regulator/rk808-regulator.c:97:2: error: implicit declaration of function 'gpiod_get_value' [-Werror=implicit-function-declaration]
if (IS_ERR(gpio) || gpiod_get_value(gpio) == 0)
^
