sh: migrate to arch/sh/include/

Browse Source 
This follows the sparc changes a439fe51a1.

Most of the moving about was done with Sam's directions at:

http://marc.info/?l=linux-sh&m=121724823706062&w=2

with subsequent hacking and fixups entirely my fault.

/*
* Encoded IRQs are not considered worth to be supported.
* Main reason is that there's no per-encoded-interrupt
* enable/disable mechanism (as there was in SH3/4).
* An all enabled/all disabled is worth only if there's
* a cascaded IC to disable/enable/ack on. Until such
* IC is available there's no such support.
*
* Presumably Encoded IRQs may use extra IRQs beyond 64,
* below. Some logic must be added to cope with IRQ_IRL?
* in an exclusive way.
*
* Priorities are set at Platform level, when IRQ_IRL0-3
* are set to 0 Encoding is allowed. Otherwise it's not
* allowed.
