msm: vidc: Convert all mallocs in *_res_parse.c to managed mallocs

The functions in *_res_parse.c are called exclusively within the context
of the device probe.  As a result the alloced memory is held over the
lifetime of the driver. As this memory is never realistically freed,
kmemleak falsely flags these as memory leaks.  This commit turns these
allocations into devm_kmallocs as a hint to kmemleak that these aren't
really memory leaks.
