[U-Boot] [PATCH] Tegra30: Cardhu: Remove unneeded cardhu.c.mmc file

[Tom Warren]

This was an older debug/developmental file that got added
accidentally. Not needed/used in any Cardhu build.

Signed-off-by: Tom Warren <twarren at nvidia.com>

This errant file exists in u-boot-tegra/next, u-boot-arm/master, and
u-boot/master (TOT). I'll remove it from u-boot-tegra/next, so it'll
trickle upstream into ARM and TOT U-Boot, or those custodians can apply
this patch and remove it now if they wish.
