gpu: ipu-v3 ipu-cpmem: Remove unused functions

ipu_cpmem_set_yuv_interleaved() was added in 2012 by
commit 0125f21b2baf ("staging: drm/imx: Add
ipu_cpmem_set_yuv_interleaved()")
but has remained unused.

ipu_cpmem_get_burstsize() was added in 2016 by
commit 03085911d7bb ("gpu: ipu-cpmem: Add ipu_cpmem_get_burstsize()")
but has remained unused.

Remove them.
