ath9k_hw: remove wrapper ath9k_hw_write_regs()
This is used only once by ath9k_hw_process_ini() to write an array of phy registers through REG_WRITE_ARRAY(), but we already call REG_WRITE_ARRAY() multiple times on the same caller so just remove this pointless wrapper. We'll eventually just move the ath9k_hw_process_ini() caller as an callback to abstract away between different hardware families. Although this change is subtle I should note that this does change the delay pattern on writing the next series of registers. REG_WRITE_ARRAY() uses a counter for each register write and does a udelay(1) every 64 writes. By removing this call it means that the counter is processed for all the iniBB_RfGain registers and is incremented on ath9k_hw_process_ini(), before this the after the call ath9k_hw_write_regs() was made the register counter was kept at the same index number prior to the call.
