Please use devm_reset_control_get_exclusive() or

Please just return errors here instead of ignoring them.
The reset_control_get_optional variants return NULL in case the
device node doesn't contain a resets phandle, in case you really
consider this reset to be optional even though the flag is set?

It feels like we should get rid of the flag and leave it to the 
devicetree.

I'm still kind of surprised it's not something we want to do for the 
2400 and 2500 as well.
