Dan Williams 49b532f96f Revert "serial/8250_pci: setup-quirk workaround for the kt serial controller" ... This reverts commit 448ac154c9. The semantic of UPF_IIR_ONCE is only guaranteed to workaround the race condition in the kt serial's iir register if the only source of interrupts is THRE (fifo-empty) events. An modem status event at the wrong time can again cause an iir read to drop the 'empty' status leading to a hang. So, revert this in preparation for using the existing "I don't trust my iir register" workaround in the 8250 core (UART_BUG_THRE).
