Subject: [RESEND PATCH v2] leds: syscon: Support 'reg' in addition to 'offset' for register address

The register-bit-led binding now also supports 'reg' in addition to
'offset' for the register address. Add support to the driver to get the
address from 'reg'.

The binding change landed, but v2[1] was never applied.
