[PATCH] OMAP: Fix linking error in twl-common.c for OMAP2/3/4 only builds

[Peter Ujfalusi]

Avoid compiling code for OMAP arch which is not selected by the
config.

Fixes issues like:
With CONFIG_ARCH_OMAP3=y and CONFIG_ARCH_OMAP4=n, I'm getting this:

arch/arm/mach-omap2/built-in.o:(.data+0xf99c): undefined reference to `omap4430_phy_init'
arch/arm/mach-omap2/built-in.o:(.data+0xf9a0): undefined reference to `omap4430_phy_exit'
arch/arm/mach-omap2/built-in.o:(.data+0xf9a4): undefined reference to `omap4430_phy_power'
arch/arm/mach-omap2/built-in.o:(.data+0xf9a8): undefined reference to `omap4430_phy_set_clk'
arch/arm/mach-omap2/built-in.o:(.data+0xf9ac): undefined reference to `omap4430_phy_suspend'

Hi Russel, Tony,

This patch fixes the linking error caused by the twl-common.c file,
when the kernel is built for OMAP2/3/4 only.

Regards,
Peter
