[U-Boot] [PATCH v2] MX51: mx51evk: Use struct to access SRSR register instead of offset

[Fabio Estevam]

Use struct to access SRSR register instead of offset. While at it mask 
the 7 bits of SRSR for correctness.

Signed-off-by: Fabio Estevam <fabio.este...@freescale.com>

Changes since v1:
- Use readl to read the srsr register
- Mask the lower 7 bits of the SRSR register for
getting the correct result.
