mmc: sdhci-brcmstb: Fix mmc timeout errors on S5 suspend

Browse Source 
commit 5b191dcba719319148eeecf6ed409949fac55b39 upstream.

Commit e7b5d63a82 ("mmc: sdhci-brcmstb: Add shutdown callback")
that added a shutdown callback to the diver, is causing "mmc timeout"
errors on S5 suspend. The problem was that the "remove" was queuing
additional MMC commands after the "shutdown" and these caused
timeouts as the MMC queues were cleaned up for "remove". The
shutdown callback will be changed to calling sdhci-pltfm_suspend
which should get better power savings because the clocks will be
shutdown.
