regulator: MAX20086: add gpio/consumer.h 

max20086-regulator.c needs <linux/gpio/consumer.h> for an enum, some
macros, and a function prototype. (seen on ARCH=m68k)

Adding this header file fixes multiple build errors:

../drivers/regulator/max20086-regulator.c: In function 'max20086_i2c_probe':
../drivers/regulator/max20086-regulator.c:217:26: error: storage size of 'flags' isn't known
  217 |         enum gpiod_flags flags;
../drivers/regulator/max20086-regulator.c:261:27: error: 'GPIOD_OUT_HIGH' undeclared (first use in this function); did you mean 'GPIOF_INIT_HIGH'?
  261 |         flags = boot_on ? GPIOD_OUT_HIGH : GPIOD_OUT_LOW;
      |                           ^~~~~~~~~~~~~~
../drivers/regulator/max20086-regulator.c:261:44: error: 'GPIOD_OUT_LOW' undeclared (first use in this function); did you mean 'GPIOF_INIT_LOW'?
  261 |         flags = boot_on ? GPIOD_OUT_HIGH : GPIOD_OUT_LOW;
../drivers/regulator/max20086-regulator.c:262:27: error: implicit declaration of function 'devm_gpiod_get'; did you mean 'devm_gpio_free'? [-Werror=implicit-function-declaration]
  262 |         chip->ena_gpiod = devm_gpiod_get(chip->dev, "enable", flags);
../drivers/regulator/max20086-regulator.c:217:26: warning: unused variable 'flags' [-Wunused-variable]
  217 |         enum gpiod_flags flags;
