ARM: OMAP2+: Remove board file for H4
The old 2420 based H4 is probably not used at all as 2420 was Nokia specific SoC. I have one, but I'm not using it because of it's large size, and I doubt anybody else is using it either. We do have minimal omap2420-h4.dts in place, so if anybody wants more support on H4, patches are welcome. So let's just remove it as that helps us making mach-omap2 to be device tree only.
