We have the 'ti,davinci-chipselect' property in the device tree, but
when using platform data the driver silently uses the id field of
struct platform_device as the chipselect. This is confusing and we
almost broke the nand support again recently after converting the
platform to common clock framework (which changed the device id in the
clock lookup - the problem is gone now that we no longer acquire the
clock in the nand driver.

This patch adds a new filed - core_chipsel - to the platform_data.
s/filed/field

Subsequent patches will convert the platforms to using this new field.
Can you add a comment for this new field too, like how we have for most
other fields?

Curious on what 'core' in core_chipsel means. Something to do with
chip-select offset we have on DA850?
Looks like you may have just picked the terminology from DaVinci NAND
driver (introduced back in 2009). But in this context, it means the
0-indexed chip-select number that of the asynchronous memory interface
to which the NAND device is connected.

So, may be a comment here will suffice.

Thanks,
Sekhar
