Hi all,
omap hsmmc driver is always complaining about the debounce clock. The
clock it's trying to get is not listed in clock34xx.c, the following
patch gets rid of debounce clock warning by adding the clock to the
clock list.
ps: it's RFC since I'm not really sure if it's the right clock although
docs says it's the functional 32k clock. Comments??

Subject: [RFC PATCH] ARCH: OMAP3: Missing mmc debounce clock
This clock was missing from clock34xx.c so mmc was
unable to get it on omap_hsmmc.c giving us an uneeded
warning.
