Needs module name in help text, as is the case with spacemit-pmic.

If this driver is compiled as a module, it needs to be found by modalias
so the driver auto-loads after spacemit-pmic registers the regulator
device, so you need:

+MODULE_ALIAS("platform:spacemit-p1-regulator");

Also, consider extracting the name to a macro:

#define DRV_NAME "spacemit-p1-regulator"

Also, consider naming this consistently: "spacemit-p1", or
"spacemit-p1-regulator"?
