sh: cache: don't modify CCR from P1 area

cache_wback_all() is a local function and it is called from
cache_control() only, which is in turn jumps to P2 area.

The change fixes an issue when cache_wback_all() returns from P2 to
P1, however cache_control() continues to manipulate with CCR
register, according to the User's Manual this is restricted.
