mfd: da9052-core: Fix platform-device id collision
Allow multiple DA9052 regulators be registered by registering with
PLATFORM_DEVID_AUTO instead of PLATFORM_DEVID_NONE.
The subdevices are currently registered with PLATFORM_DEVID_NONE, which
will cause a name collision on the platform bus when multiple regulators
are registered:

Based on the fix done by Johan Hovold at commit b6684228726cc255 ("mfd:
viperboard: Fix platform-device id collision").
Tested on a imx53-qsb board, where multiple DA9053 regulators can be
successfully probed.
