This patch overrides nand ecc layout and bad block descriptor (for 8-bit
device) to support hw ecc in romcode layout. So as to have in sync with ecc
layout throughout; i.e. x-loader, u-boot and kernel.
This enables to flash x-loader, u-boot, kernel, FS images from kernel itself
and compatiable with other tools.
This patch does not enables this feature by default and need to pass from
board file to enable for any board.

Cleans up all base address definitions for omap_mcspi
and adapts the device registration and driver to hwmod framework.
Changes involves:
1) Removing all base address macro defines.
2) Using omap-device layer to register device and utilizing data from
hwmod data file for base address, dma channel number, Irq_number,
device attribute(number of chipselect).
3) Appending base address with pdata reg_offset for omap4 boards.
For omap4 all regs used in driver deviate with reg_offset_macros
defined with an value of 0x100. So pass this offset through pdata
and append the same to base address retrieved from hwmod data file
and we are not mapping *_HL_* regs which are not used in driver.

- 8 x regular timer (3, 4, 5, 6, 7, 8, 9 & 11)

The regular timers registers programming model was changed due to the

still use the previous programming model. The driver will have
to take care of theses differences.
Please note that the capability and the partitioning is also
different depending of the instance.
