* libchip/ide/ata.c, c/src/libchip/ide/ata_internal.h: Remove the
multiblock support from the ATA driver. Multiblock at the disk
level should not be a global policy as a disk may have more than
one partition with different block sizes. An IDE driver could
decide to use the feature with DMA but this a driver specific
design choice. Fixed bugs relating to variable block sizes and
large block transfer.
* c/src/libchip/ide/ide_controller.c,
c/src/libchip/ide/ide_ctrl_cfg.h, c/src/libchip/ide/ide_ctrl_io.h:
Changed the block size to 32bits so blocks of 64K or bigger can be
transfered in a single driver call.
