ARM: 6764/1: pl011: factor out FIFO to TTY code

Browse source

This piece of code was just slightly different between the DMA
and IRQ paths, in DMA mode we surely shouldn't read more than
256 character either, so factor this out in its own function and
use for both DMA and PIO mode.

Tested on Ux500 and U300.
