Hmm well omap2420 does not have twl, but 2430 usually has. So do you
mean that 2430 does not use the external voltage controller code?

To avoid patching this piece of code for new SoCs, can we make it
ifndef CONFIG_ARCH_OMAP2? Also in the makefile we should not even
build twl-common.o for 2420 only builds..
