This change is similar to commit 3da355c(ARM: dts: Disable MDMA1 node
for arndale-octa board). If MDMA1 region is configured with secure mode,
it makes the boot failure with the following.
Unhandled fault: imprecise external abort (0x1406) at 0x00000000

If so, how about adding the 'disabled' status in 5420 dtsi file? Then if 'enabling' is required, we can enable in each board dt file...

That should be okay. While at it, we can remove the node disabling
code from Arndale-Octa board DTS file.

Please move the comments for MDMA1 from Arndale-Octa dts file too.
Thanks.
