The controller has interrupt enable/status register pairs for each bank
(along with ECC and status registers) that differ only in address offset.
Rather than providing definitions for each register, make the address a
macro so that it scales for devices with different numbers of banks.

Rather than using the PCI specific DMA API, convert to the generic
DMA API so that we can use the Denali NAND controller on other bus
types.

set_ecc_config function only set ECC_CORRECTION register, so
move register setting to probe function.
Since controller only support 15bit and 8bit ecc correction,
updated nand ecc layout information.

Fix all checkpatch.pl complaints.

Artem: tweaked a little and fix tab indentations, so now this is not
       only about checkpatch, but also about making indentations look
       sane.
