tegra mmc: enable MMC_UNSAFE_RESUME config for tegra_whistler_gnu_linux
Normally, when the system goes into suspend, all the storage cards are
removed and later re-enumerated upon resume. During re-enumeration the
device name and number are not guaranteed to be the same as they were
during bootup. This can cause issues if rootfs falls on one such
device.
When the MMC_UNSAFE_RESUME config is enabled, it will prevent kernel
from unmounting the mmc cards before suspend. Upon resume the cards
will still be using the same device id as they were before suspend.
