sh: Consolidate Kconfig.sh/Kconfig.sh64.
Fold in the sh64-specific bits in to the main Kconfig.sh, and move this back as arch/sh/Kconfig. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

- Find out whether you have a PCI motherboard. PCI is the name of a
- bus system, i.e. the way the CPU talks to the other stuff inside
- your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
- VESA. If you have PCI, say Y, otherwise N.
-
- The PCI-HOWTO, available from
- <http://www.tldp.org/docs.html#howto>, contains valuable
- information about which PCI hardware does work under Linux and which
- doesn't.

- depends on PCI
- default y
- help
- Enable this option if your platform does not have a CPU cache which
- remains coherent with PCI DMA. It is safest to say 'Y', although you
- will see better performance if you can say 'N', because the PCI DMA
- code will not have to flush the CPU's caches. If you have a PCI host
- bridge integrated with your SH CPU, refer carefully to the chip specs
- to see if you can say 'N' here. Otherwise, leave it as 'Y'.
