Doug Brown 5208e7ced5 serial: 8250_pxa: Configure tx_loadsz to match FIFO IRQ level ...

The FIFO is 64 bytes, but the FCR is configured to fire the TX interrupt
when the FIFO is half empty (bit 3 = 0). Thus, we should only write 32
bytes when a TX interrupt occurs.

This fixes a problem observed on the PXA168 that dropped a bunch of TX
bytes during large transmissions.

Fixes: ab28f51c77 ("serial: rewrite pxa2xx-uart to use 8250_core")
