When dealing with filesystems that come from block devices we can get a
noticeable performance gain in some use cases from having the block
cache enabled. The code paths are valid in other cases when we have BLK
set and may provide wins in raw reads in some use cases, so have this be
default when BLK is enabled.

- Make this default y, unconditionally but depend on BLK which is
required for the functionality to be used.

This is most useful when accessing filesystems under U-Boot since
