remoteproc: elf_loader: skip segment with memsz as zero
Per elf specification,
p_filesz: This member gives the number of bytes in the file image of
the segment; it may be zero.
p_memsz: This member gives the number of bytes in the memory image
of the segment; it may be zero.
There is a case that i.MX DSP firmware has segment with PT_LOAD and
p_memsz/p_filesz set to zero. Such segment needs to be ignored,
otherwize rproc_da_to_va would report error.
