[BACKPORT 4.4.y 07/25] mmc: sanitize 'bus width' in debug output

[Arnd Bergmann]

From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>

The bus width is sometimes the actual bus width, and sometimes indices
to different arrays encoding the bus width. In my debugging case "2"
could mean 8-bit as well as 4-bit, which was extremly confusing. Let's
use the human-readable actual bus width in all places.
