rt2x00: rt2800lib: fix antenna configuration for RT3593

Browse Source 
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.

  RT3593_CONFIG_SET_BY_ANTENNA in include/chip/rt3593.h
