gpu: ipu-cpmem: set image base address even for incorrect formats

Browse source

Otherwise, if the image base address is kept at zero, and if the user
ignores the error return value, the IPU may be configured to write into
the dma-apbh@00110000 region for large frames, which will lock up the
system.
