From: Konrad Dybcio <konrad.dybcio@oss.qualcomm.com>
Cheza was a prototype board, used mainly by the ChromeOS folks, whose
former efforts on making linux-arm-msm better we greatly appreciate.
There are close to zero known-working devices at this point in time
(see the link below) and it was never productized.
Remove it to ease maintenance burden.

What about compatible bindings? If this is the last user, it should be
dropped as well (second patch).
