[PATCH] regulator: mcp16502: Include linux/gpio/consumer.h to fix build error

[Axel Lin]

Fix below build error:
drivers/regulator/mcp16502.c: In function âmcp16502_gpio_set_modeâ:
drivers/regulator/mcp16502.c:135:3: error: implicit declaration of function âgpiod_set_valueâ; did you mean âgpio_set_valueâ? [-Werror=implicit-function-declaration]
   gpiod_set_value(mcp->lpm, 0);
   ^~~~~~~~~~~~~~~
   gpio_set_value
drivers/regulator/mcp16502.c: In function âmcp16502_probeâ:

             ^~~~~~~~~~~~~~

drivers/regulator/mcp16502.c:486:40: error: âGPIOD_OUT_LOWâ undeclared (first use in this function); did you mean âGPIOF_INIT_LOWâ?
  mcp->lpm = devm_gpiod_get(dev, "lpm", GPIOD_OUT_LOW);
