Ulf Hansson 2501c9179d mmc: core: Use MMC_UNSAFE_RESUME as default behavior
Invoking system suspend or shutdown without using the Kconfig option
MMC_UNSAFE_RESUME, did trigger an ungraceful power cut of the card.

To improve the situation, change the behavior to always make use of the
available bus_ops callbacks that handles system suspend and shutdown
properly.

By changing the behavior MMC_UNSAFE_RESUME becomes redundant, so lets's
remove it.

bool "MMC host clock gating"
help
This will attempt to aggressively gate the clock to the MMC card.
This is done to save power due to gating off the logic and bus
noise when the MMC card is not in use. Your host driver has to
support handling this in order for it to be of any use.
If unsure, say N.
