blk: Use a function for whether block devices are available
At present we use HAVE_BLOCK_DEVICE to indicate when block devices are available. This is a very strange option, since it partially duplicates the BLK option used by driver model. It also covers both U-Boot proper and SPL, even though one might have block devices and another not. As a first step towards correcting this, create a new inline function called blk_enabled() which indicates if block devices are available. This cannot be used in Makefiles, or #if clauses, but can be used in C code. A function is useful because we cannot use CONFIG_IS_ENABLED(BLK) to decide if block devices are needed, since we must consider the legacy block interface, enabled by HAVE_BLOCK_DEVICE Update a few places where it can be used and drop some unnecessary #if checks around some functions in disk/part.c - rely on the compiler's dead-code elimination instead.
