[PATCH] ARM: omap: make am43xx build with SMP enabled

[Arnd Bergmann]

With am43xx enabled, omap4 and omap5 disabled and SMP on, I get these
build errors:

arch/arm/mach-omap2/built-in.o: In function `scu_gp_set':
:(.text+0x7858): undefined reference to `omap4_get_scu_base'
arch/arm/mach-omap2/built-in.o: In function `scu_gp_clear':
:(.text+0x793c): undefined reference to `omap4_get_scu_base'
arch/arm/mach-omap2/built-in.o: In function `omap4_cpu_die':
:(.ref.text+0x44): undefined reference to `omap4_hotplug_cpu'

The easiest way to work around that is to turn on the missing
functions, even though we know they won't be used on am43xx,
which is single-CPU.
