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

This patch reworks the sh3/sh4/sh4a register saving code in
the following ways:
- break out prepare_stack_save_dsp() from handle_exception()
- break out save_regs() from handle_exception()
- the register saving order is unchanged
- align new functions to fit in cache lines
- separate exception code from interrupt code
- keep main code flow in a single cache line per exception vector
- use bsr/rts for regular functions (save pr first)
- keep data in one shared cache line (exception_data)
- document the functions
- tie in the hp6xx code

Move the not-so-generic pm code from arch/sh/kernel/pm.c to the
platform directory together with the rest of the hp6xx pm code.
This is done to let non-hp6xx platforms enable CONFIG_PM.

This flattens out the board directories in to individual mach groups,
we will use this for getting rid of unneeded directories, simplifying
the build system, and becoming more coherent with the refactored
arch/sh/include topology.
