Really Fix remoteproc to work with the PRU GNU Binutils port

The original patch has been mistakenly applied to DRAM addresses,
whereas IRAM are the ones needing a fixup.

This patch fixes the following error:
  [ 1672.917602] remoteproc remoteproc1: Booting fw image pru-core0.elf, size 7104
  [ 1672.917632] remoteproc remoteproc1: bad phdr da 0x20000000 mem 0x8f4
  [ 1672.929347] remoteproc remoteproc1: Failed to load program segments: -22
  [ 1672.938733] remoteproc remoteproc1: Boot failed: -22
