Reset controller fixes for v4.11

Fix devm_reset_controller_get_optional to return NULL for non-DT devices,
if the RESET_CONTROLLER Kconfig option is enabled. This fixes probe failures
of the 8250_dw driver on Intel platforms after commit acbdad8d

 ("serial:
8250_dw: simplify optional reset handling").
