mfd: ti_am335x_tscadc: Use PLATFORM_DEVID_AUTO while registering mfd cells

[ Upstream commit b40ee006fe6a8a25093434e5d394128c356a48f3 ]

Use PLATFORM_DEVID_AUTO to number mfd cells while registering, so that
different instances are uniquely identified. This is required in order
to support registering of multiple instances of same ti_am335x_tscadc IP.
