[U-Boot] [PATCH] ARM: dts: logicpd som-lvs and torpedos: Shrink SPL DTB

[Adam Ford]

Since we have limited resources in SPL, it is the best interest
to keep the SPL as small as possible and that includes the DTB.
There are a few items in the device tree that can be removed,
because these boards don't use them.
