[PATCH] ARM: ux500: disable msp2 node on Snowball

Analogous to commit 8858d88a25142544843869f0cd3e6654aa7b4aec
that fixed commit 70b41abc151f9
"ARM: ux500: move MSP pin control to the device tree"
accidentally activated MSP2, giving rise to a boot scroll
scream as the kernel attempts to probe a driver for it and
fails to obtain DMA channel 14.

For some reason I forgot to fix this on the Snowball. Fix
this up by marking the node disabled again.

ARM SoC folks: please apply this patch directly to fixes for
v3.17, I have no other pending Ux500 fixes.

Tested on snowball, and applied to fixes.

Thanks,

Kevin
