Insert RF chipset values for the RF302x chipsets. Mirrored from the rt2800usb driver.
Also, ensure these RF chipsets are handled properly in rt2800lib for the rt3090 chipset.

This one clashes with the patch series sent by Bart. However, I believe that logically this patch
belongs before his patch series, as it makes the unification cleaner and clearer.

The change itself is correct and much welcomed but please take a look
at the diffstat below:

I worry that applying this patch before unification will not make anything
cleaner, especially since it duplicates code that unification patch will now
have to also remove:

Some previous patches also cleaned up the code below (by using 'chip'
variable) so this patch could have been smaller and easier to review
by simply basing it on the previous work.

Please also note that previous patches were tested, reviewed and many
agreed on already (i.e. unification patch has Ivo's ACK) so unfortunate
side effect of not doing changes in the incremental fashion is that
people will be needlessly required to invest time on testing & reviewing
modified patches..

Please reconsider re-basing your work on top of changes from:

	git://git.kernel.org/pub/scm/linux/kernel/git/bart/misc.git rt2800

Thanks.

I agree that the patch in itself won't make things cleaner. However, my argument was that applying this
patch before unification would make the unification patch cleaner and clearer (i.e. it would be more
obvious that there is a large degree of overlap).

However, since I am such a nice guy, I will respin my 2 of my patches (the RT3070 detection for rt2800usb
and this one) to apply on top of your patch series.
