[PATCH v2 5/6] ARM: mxc: all three imx51 TOs use TO1 version of sdma script

Though there are three TOs of imx51 soc, the sdma script never
changes since TO1, which means all three TOs of imx51 uses TO1
version of sdma script.

The current code passes TO number to imx-sdma driver to load
different firmware for different TO.  That means we have to prepare
3 identical firmwares, sdma-imx51-to1.bin sdma-imx51-to2.bin and
sdma-imx51-to3.bin, to have the kernel capable of running on all
three TOs.  This just makes no sense.

The patch removes the TO number passing and get the default TO1
version of sdma firmware work for all TOs.

Changes since v1:
 * fix typo in imx51 firmware name caught by Fabio Estevam
