mmc: core: Fix disabling of cache for Hynix cards

Commit 6932a01c (mmc: card: quirk: disable cache for Hynix card)
claims to disable cache because of data corruption issues when cache
it is enabled. In reality, the patch allows enabling of cache during
card initialization but disallow flushing of cache during suspend or
file system sync operations. This is more dangerous than without
the commit. Move the fixups for disabling cache to mmc_fixups so as
to enable the quirk during initialization itself. Also, remove obvious
warnings everytime card is initialized during runtime resume.
