Modified Files:
        src/sys/arch/arm/omap: omap3_sdhc.c

Log Message:
AM335x EDMA3 has an alignment restriction for both SAM and DAM in constant
addressing mode. In these cases, the physical address must be aligned to
256-bits. To handle this, pre-allocate a MAXPHYS sized bounce buffer and
use it for unaligned transfers.

Fixes "edma errint!" problem mentioned in port-arm/50288.
