MLK-17991-5 gpu: imx: dpu: common: Add basic fetchwarp2 support

Fetchwarp is a type of dpu fetch unit with the additional
warping function.  Each fetchwarp contains 8 subsidiary layers.
Fetchwarp2 can work with fetcheco2 to fetch planar YUV pixel
formats.  Also, it may fetch RGB pixel formats.  This patch
adds basic fetchwarp2 fetch unit support in the dpu common driver
so that it may fetch frames in RGB pixel formats.  YUV pixel formats
and warping function could be supported later.
