Subject: [PATCH v2 1/2] mfd: ti_am335x_tscadc: Use PLATFORM_DEVID_AUTO while registering mfd cells

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.

v2: use PLATFORM_DEVID_AUTO as suggested by Lee Jones
