[PATCH] amba-pl010: clear error flags on rx error
The pl010 primecell documentation specifies that an error indicated via RSR
should be cleared by a write to ECR. We didn't do this, which was causing
errors to be re-reported on every call to pl010_rx_chars().
Doing a write to ECR once we detect an error appears to prevent the ep93xx
console UART driver from going into a mode where it reports "ttyAM0: X
input overrun(s)" every couple of keystrokes.
