mtd: nand: ams-delta: drop omap_read/write, use ioremap

There is a common requirement for not using OMAP specific omap_readw() /
omap_writew() function calls in drivers/, but replace them with
readw() / writew() on ioremap()ped addresses passed from arch/ instead.

The patch implements this idea for the Amstrad Delta NAND driver. To be
able to use the modified driver, the board file is updated with the
platform device I/O resource declaration, which is passed from there.

Created and tested against linux-2.6.37-rc5, on top of recent patch
'MTD: NAND: ams-delta: convert to platform driver'.
