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.

	  Compact Flash is a small, removable mass storage device introduced
	  in 1994 originally as a PCMCIA device.  If you say `Y' here, you
	  compile in support for Compact Flash devices directly connected to
	  a SuperH processor.  A Compact Flash FAQ is available at
	  <http://www.compactflash.org/faqs/faq.htm>.

	  If your board has "Directly Connected" CompactFlash at area 5 or 6,
	  you may want to enable this option.  Then, you can use CF as
	  primary IDE drive (only tested for SanDisk).

	  If in doubt, select 'N'.

	  - "Area5" if CompactFlash is connected to Area 5 (0x14000000)
	  - "Area6" if it is connected to Area 6 (0x18000000)

	  "Area6" will work for most boards.
