Subject: [PATCH 1/2] rtl8180: sync radio V2 code with vendor reference

From: Andrea Merello <[email protected]>

We have to set ofdm register 0x2 to 0x62 (0x64 is for rtl8187). We did this
correctly in init function, but we overwrite it when setting TX power.
As reference code suggest, we still rewrite it, but with right value.

The radio seems to work fine despite this message. Remove it for now.
