[PATCH] regulator: Convert to subsys_platform_driver()

[PATCH] regulator: Convert to subsys_platform_driver()

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

Replace the open-coded subsys_initcall()/module_exit() platform driver
registration with subsys_platform_driver().

No functional change.
