Bluetooth: hci_ath: Replace mdelay with msleep in ath_wakeup_ar3k
ath_wakeup_ar3k() is never called from atomic context.
It is only called by ath_hci_uart_work() that is only called in
ath_open() via INIT_WORK().
All of the above functions do not enter atomic context along the way.
Despite never getting called from atomic context, ath_wakeup_ar3k() calls
mdelay() for busy wait.
That is not necessary and can be replaced with msleep to avoid busy wait.
This is found by a static analysis tool named DCNS written by myself.
