We currently decide whether we need to descend into the subdirs of
drivers/ in drivers/Makefile, but link the resulting objects from
the top-level Makefile.

Making these two decisions at the same time (in drivers/Makefile) cleans
up the top-level Makefile quite a bit.

Link order does not change at all apart from sound/, which is now linked
last.

New driver for Micro Memory NVRAM module

This driver handles up to 16 PCI based NVRAM cards
from MicroMemory.
Each card appears like a block device, and can be partitioned
using any standard partitioning tool.  Upto 15 partitions are
supported.

This driver needs its own major device number and so allocates
one using register_blkdev.
