Enable LCDC deferred io on Migo-R using 1s delay.

As with other deferred io frame buffers user space code should
use fsync() on the frame buffer device to trigger an update.

Add LCDC interrupt resources for AP325 and Migo-R. The LCDC driver does
not require interrupts at this point, but changes such as one-shot SYS
mode using deferred io, and wait-for-vblank will both need this.

This enables the same functionality that sh64 has for sh32. When running
on simulated hardware or via remote memory via the debug interface,
memory is gauranteed to be zero on boot already, and skipping the zeroing
of BSS has measurable boot time benefits.

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.

This can use the same implementation as sh64, the generated assembly is
the same between the new and old version, so there is not much point in
leaving it open coded in inline assembly.

With the reworked kgdb support, we always detach and reinitialize the
stub. This was mostly a feature for handoffs between sh-ipl+g and the
kgdb stub, but virtually no sh-ipl+g versions ever had this working
right in the first place.

Given that the sh-ipl+g stubs in general use today don't even support
the GDB stub, and we have already killed off the special casing in the
sh-sci serial driver, kill off this now unused symbol too.

Switch the dreamcast IRQ code over to the irq_chip way of doing things,
so that we can set GENERIC_HARDIRQS_NO__DO_IRQ for all SuperH boards.

Also, whilst I'm here change some things to make checkpatch.pl happy:
	- Indent with tabs, not with spaces
	- Include <linux/io.h>, not <asm/io.h>
	- Fix the multi-line comment style
	- Fix some typos in the comments
