ARM: pxa: remove Intel Imote2 and Stargate 2 boards

Browse Source 
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!
