[PATCH] mioa701: add newly available DoC G3 chip

[Robert Jarzmik]

From: Robert Jarzmik <robert.jarzmik@atosorigin.com>

As the mioa701 board has a M-Systems DiskOnChip G3 chip, add
it to the platform resources of the board.

You resized the flash from 64MB to 8KB. It surprised me that the flash
size is only 8KB. Could you help to check this?

Checked and confirmed, it's 8K.
The docg3 has a mapped IO space, where :
 - 0x0 - 0x7ff     : boot memory (NOR like)
 - 0x800 - 0xfff   : data area
 - 0x1000 - 0x17ff : registers area
 - 0x1800 - 0x1fff : boot memory (the same one as before)

And the previous "64MB" was because I didn't know which kind of memory was
there, and a static bank can be as big as 64MB.

Cheers.
