Platform data for device drivers should be defined in
include/linux/platform_data/*.h, not in the architecture
and platform specific directories.
This moves such data out of the davinci include directories

aemif_calc_rate() can return a negative error value, so all the
variables that get tested for this value need to be signed.
The maximum bit width of WSETUP(WSETUP_MAX) appears to be 30 bits
(0xf << 26). Using a signed instead of an unsigned integer
shouldn't make a difference here.

This patch adds support to configure the AEMIF interface
with supplied timing values.
Since this capability is useful both from NOR and NAND
flashes, it is provided as a new interface and in a file
of its own.
AEMIF timing configuration is required in cases:
1) Where the AEMIF clock rate can change at runtime (a side
affect of cpu frequency change).
2) Where U-Boot does not support NAND/NOR but supports other
media like SPI Flash or MMC/SD and thus does not care about
setting up the AEMIF timing for kernel to use.
3) Where U-Boot just hasn't configured the timing values and
cannot be upgraded because the box is already in the field.
Since there is now a header file for AEMIF interface, the
common (non-NAND specific) defines for AEMIF registers have
been moved from nand.h into the newly created aemif.h
