v3 Changes:
As requested by Artem Bityutskiy, I have seperated out the flash chip data into
a seperate file (flash_jedec.(h/c)) which should be expandable by other drivers
as needed.

I have also cleared up some of the sparse warnings that were being generated,
but need some help with the last one:
+drivers/mtd/devices/wmt_sflash.c:442:24: warning: cast removes address space of expression [sparse]
which relates to this line:
+	u32 addr_to = (u32)info->sf_base_virt + to;

What is the correct way to get the value of ->sf_base_virt without generating
a sparse warning? sf_base_virt is void __iomem *.
