Subject: [PATCH v2] mmc: correct one comment error of structure mmc_ext_csd

From: "Zhang, Yi" <yix.x.zhang@...il.com>

The right value for field raw_exception_status is 54(not 53) according
to eMMC 4.5 specification. Also for more readable, replace all number
values with macro symboles.

Signed-off-by: Zhang, Yi <yix.x.zhang@...il.com>
