Paul Sokolovsky 45b1d73164 drivers: serial: uart_cmsdk_apb: Ack IRQs before callback to avoid races 
This effectively reverts part of earlier 49bb163756 which moved
interrupt acknowledgement until after return from the user callback.
This was done confusing the flow of this driver with how some other
drivers do it, where pending interrupt status is checked by
uart_irq_rx_ready()/uart_irq_tx_ready(), which should be called by
the callback. But the uart_cmsdk_apb driver actually uses different
hardware register in these functions. And acking IRQs after user
callback can lead to race condition and losing an IRQ, and the
simple fix in this case is just move acknowledgement to where it
was before.
