[yocto] [PATCH] yocto-bsp: Fix QEMUARM based bsps to not offer SMP support

The SMP kernel config presents issues on qemuarm because:
CONFIG_SMP=y
Dependencies Missing:
- CPU_V6K or CPU_V7:
These are selected by setting:
CONFIG_ARCH_MULTI_V7=y
or
CONFIG_ARCH_MULTI_V6=y
But our QEMU + ARM BSPs are based on armv4/v5 hence they are
incompatible with CONFIG_SMP.
This patch fixes the script, and avoids offering SMP to the user
when the created BSP is based on QEMU + ARM.
