Add some flags for the heartbeat driver, and kill off some duplication
in the bit positions for the boards that don't have special cases.

This also allows for variable access widths and inversion.

This patch cleans up solution engine 7722 specific interrupt code.
The main purpose is to replace the mux function with use of
set_irq_chained_handler() and replace hard coded register poking
code with set_irq_type(). The board specific interrupts are also
moved to start from SE7722_FPGA_IRQ_BASE.

We now throw all of the machvecs in to .machvec.init and either
select one on the command line, or copy out the first (and
usually only) one to sh_mv. The rest are freed as usual.

This gets rid of all of the silly sh_mv aliasing and makes the
selection explicit rather than link-order dependent.

This adds more full-featured support for the SH7722 Solution Engine.
Previously this was using the generic board, and lacked most of the
peripheral support.
