The max20086 regulator driver includes the legacy header
<linux/gpio.h> for no reason, it is already using the proper
<linux/gpio/consumer.h> include. Drop the include.

After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS
for drivers that existed in 4.14") but changes regulators didn't exist
in Linux 5.15 but did exist in Linux 6.1.

The driver can be compile tested with !CONFIG_OF making certain data
unused:

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:

This code accidentally returns PTR_ERR(NULL) which is success. It
should return a negative error code.

The MAX20086-MAX20089 are dual/quad power protectors for cameras. Add a
driver that supports controlling the outputs individually. Additional
features, such as overcurrent detection, may be added later if needed.
