msm: mdss: Enable Decimation during fetch
Decimation is a new mdss hardware feature that facilitates
display of images with width larger than 2048 through a single pipe.
It enables display of high resolution images on multiple interfaces
simulatenously. Also, the presence of this hardware feature needs
to be exposed to userspace so that the usecase can be supported.
