Paul Mundt 197b58e665 sh: se7343: Move CPLD IRQs to irqdomain and generic irq chip.
Follows the se7722 change, see there for more information.

Paul Mundt 5df38b9b76 sh: se722: Move FPGA IRQs to irqdomain and generic irq chip.
This implements a total rewrite of the rather buggy SE7722 FPGA IRQ code,
utilizing a linear irq domain as well as the generic irq chip type.

While the interaction between the two APIs is a bit clunky (ie, revmap
lookup for gc irq_base), they work well enough together that it's easy
enough to work with going forward.

While we're at it, deal with irq_mask_ack/unmask of the chained IRQ in
the demux handler to prevent smc91x screaming about spurious interrupts.

There's also some more improvement that can be made to the irqdomain code
to create backing irqdescs for the entire linear range in one bang
instead of iterating over the number of hwirqs and doing it
irq-at-a-time. This is easily dealt with at a later point, though.

Paul Mundt 53e6d8e006 sh: mach-se: Convert SE7343 FPGA to dynamic IRQ allocation.
This gets rid of the arbitrary set of vectors used by the SE7722 FPGA
interrupt controller and switches over to a completely dynamic set.
No assumptions regarding a contiguous range are made, and the platform
resources themselves need to be filled in lazily.

Paul Mundt 073da9c0de sh: Kill off cf-enabler with extreme prejudice.
Now that the rest of the boards that were using cf-enabler "generically"
have switched to setting up their mappings on their own, only the mach-se
boards were left using it. All of the cf-enabler using mach-se boards
use a special initialization of the MRSHPC windows rather than going
through the special PTE as other SH-4 platforms do. This consolidates
the MRSHPC setup logic, hooks it up on the boards that care, and gets rid
of any and all remaining references to cf-enabler.

This has been long overdue, as cf-enabler has been the bane of
arch/sh/kernel for the last 7 years. Good riddance.

smc91x that once must have been on a special daughterboard.
