[PATCH] regulator: dummy, make dummy_regulator_driver static

[Ben Dooks]

When converting to faux_device the dummy_regulator_driver was
made non-static however it isn't exported or defined anywhere
outside the file it is in. Make it static to avoid the following
sparse warning:

drivers/regulator/dummy.c:59:24: warning: symbol 'dummy_regulator_driver' was not declared. Should it be static?

Fixes:  dcd2a9a5550ef556c8 ("regulator: dummy: convert to use the faux device interface")
