With the sparseirq conversion there was a stray irq_desc reference left
over, this tidies it up and brings the demuxer in line with what the
solution engine boards are doing.

Follows the se7724 change and converts the hd64461 IRQ handling to
sparseirq.

The old ctrl in/out routines are non-portable and unsuitable for
cross-platform use. While drivers/sh has already been sanitized, there
is still quite a lot of code that is not. This converts the arch/sh/ bits
over, which permits us to flag the routines as deprecated whilst still
building with -Werror for the architecture code, and to ensure that
future users are not added.

Fixes several compile errors due to the recent hd64461 I/O base changes.

Signed-off-by: Paul Mundt <lethal@linux-sh.org>

hd64461 is mapped in a fixed location, so the I/O base itself is fairly
meaningless as a configuration item. Additionally, this makes it
impossible to share hd64461 code alongside generic drivers (in the case
of sh_dac_audio), so simply make it commonly defined and permit the
mach_is_foo() logic to work out the proper semantics.

Rework the hd64461 demuxer code to fix the HD64461 level-triggered
interrupts handling, using handle_level_irq() as needed.
