ARM: pxa: remove Intel Imote2 and Stargate 2 boards
I have no reason to believe these boards have any more users and I haven't tested them for several years. Removing them may simplify other changes to the various PXA boards people still care about. The recent conversion of pxa2xx_spi to GPIO descriptors for example had to update this board despite no one caring or testing. Great boards that got me started in kernel development, RIP!
