drivers: mfd: Move codec reset gpio config to early boot

Codec reset gpio configuration needs to be updated
before slimbus master component is initialized otherwise
codec cannot be enumerated on the bus. Add a new platform
device driver to update the codec reset gpio configuration
to valid state (output, drive-strength) before slimbus
is initialized.
