Subject: [PATCH] sdhci: seperate out reset so if platform specific helper 
exists it is called
 if it exists otherwise standard reset function is called.  This way the 
platform
 specific code and use the standard code if needed.

for example in our driver we need to reset some platform specific registers 
depending
on the type of reset

a) if not reset_all -> just call the helper
b) if reset_all --> call the helper then do our private stuff
