optional nit: maybe when this is applied Bjorn / Andy can put in the
actual error message to make this easier to find if anyone is seeing
this problem. Specifically:
msm ae00000.mdss: [drm:adreno_request_fw] *ERROR* failed to load
qcom/a630_zap.mdt: -2
adreno 5000000.gpu: [drm:adreno_zap_shader_load] *ERROR* Unable to
load a630_zap.mdt

I probably would have put it in two patches (one for sdm845.dtsi and
one for cheza) but that's more because I'm obsessive-compulsive than
for any real reason. ;-) In any case:
