Fixes IDE issues found on the Malta board under Qemu:

1. DMA implied commands were sent to the controller in stead of the PIO

variants. The rest of the code is DMA free and written for PIO operation.

2. direct pointer access was used to read and write the registers instead

of the inb/inw/outb/outw functions/macros. Registers don't have to be memory mapped and ATA_CURR_BASE() does not have to return an offset from address zero.

3. Endian isues in ide_ident() and reading/writing data in general. Names

were corrupted and sizes misreported.

Tested malta_defconfig and maltael_defconfig to work again in Qemu.

Applied to u-boot/master, thanks!
