- Clear the CE AFSR bits which indicate the error condition when handling
a correctable DMA error. Failing to do so can cause the error interrupt
to be triggered over and over again.
- Clean up the comments for UEAFSR_* constants, fix a typo (UEAFSR_BLK is
(1 << 23), not (1 << 22)), and add two more. Also, add similar constants
for the CE AFSR bits.
