Add support for AT45DB321C.

It seems like this model is one-of-a-kind... it shares some properties
with the older versions of the AT45DB series as well as with new ones.

Add support for AT45CS1282.

This one is even more strange than the AT45DB chips. Like the AT45DB321C
it does not support any power-of-2 page sizes. There is only one asymmetrical
eraser and that uses two opcodes.
