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.
