Subject: [PATCH] ARM: efm32: drop selecting NO_DMA

The Kconfig entry for ARCH_EFM32 selects NO_DMA. But that doesn't have
any effect as arm doesn't have a Kconfig entry for NO_DMA. This select
is a nop. Drop it.

Tested by playing with arch/arm/configs/efm32_defconfig. After "make
oldconfig" the .config contains CONFIG_HAS_DMA=y both before and after
this patch, as is expected.

Actually, the only difference I found in the .config file was that after
this patch the .config file contained
    CONFIG_ARCH_EFM32=y

I have no idea why. Did I botch my test?
