Annotate the low level hardware locks which must not be preempted.

In mainline this change documents the low level nature of
the lock - otherwise there's no functional difference. Lockdep
and Sparse checking will work as usual.

Add support for this. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

This removes the array of dma structures in the central multiplexer, replacing it with an array of pointers instead; this is more flexible since it allows the drivers to wrap the DMA structure (eventually allowing us to transition non-ISA DMA drivers away.)
