rt2x00: rt2800lib: fix antenna configuration for RT3593 



On the RT3593 chipset, BBP register 86 must be
configured by different values based on the RX
antenna numbers.

Configure this register from the 'rt2800_config_ant'
function.

Based on the Ralink DPO_RT5572_LinuxSTA_2.6.0.1_20120629
driver.
