Revert "arch: arm: set the architecture via Kconfig"

Browse source 
This reverts commit 3f6884902b.

This commit does not work as intended: the part in arch/arm/Makefile
gets ignored and -mcpu=cortex-m3/4 does not get passed to gcc. It seems
that the zephyr toolchain does not care, but the vxworks assembler
chokes if it is missing, and thinks the CPU does not support thumb ISA
