rt2x00: Add rt3090 support in rt2800 register initialization.
Browse files Browse the repository at this point in the history 
Add RT3090 specific register initializations to rt2x00, based on the latest
Ralink rt3090 vendor driver.

Untested as I don't actually own an RT3090 based device, but given experiences
on rt3070/rt3071 very hopeful that this will actually work..
