ath9k_hw: add a private callback for PLL control computation
The PLL control computation used to program the AR_RTC_PLL_CONTROL register varies between our harware so just add a private callback for it. AR9003 will use its own callback. Signed-off-by: Luis R. Rodriguez <lrodriguez@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
