ARM: mx51/sdma: Check the chip revision in run-time
Check the MX51 chip revision in run-time so that the correct SDMA firmware can
be loaded.
While at it also remove the silicon revision from the sdma_script_start_addrs
structure name for MX51. All the MX51 revisions share the same SDMA start addresses.
