Similar to sdhci-pci controller, also add probe_slot
and remove_slot method in the sdhci-acpi driver.

This is the v2 version patch and fixed checkpatch errors.

This patch did require a rebase, but I manage to resolve the conflict
while applying the patch on my next track. Please have a look at the
result. Thanks!

Also, I took the liberty of removing the information about that this
is a v2 patch from the commit message. Future wise, please don't
include that in the actual commit msg, but keep it as "patch
information".

Kind regards
Uffe

The patch looks fine to me. Thanks for the rebase work.
I'm not sure what's wrong my local mmc_next tree, maybe it's too old. I'll git clone it again.

Thanks for the education. I'll not include those kind of info in the actuall commit message in future.

Thanks.
