rt2x00: Enable WLAN LED on Ralink SoC (rt305x) devices
This patch adds WLAN LED support to the mac80211 rt2x00 driver for Ralink SoC (rt305x) devices. The current WLAN LED drivers in rt2800lib.c set the LED brightness via an MCU request, but do nothing for SoC. This patch checks for SoC and sets the register to enable the WLAN LED (instead of an MCU request). This enables the WLAN LED for RT305x devices.
