This patch will move the VM configuration check to pre-build stage,
a test program will do the check for pre-defined VM configuration
data before making hypervisor binary. If test failed, the make
process will be aborted. So once the hypervisor binary is built
successfully or start to run, it means the VM configuration has
been sanitized.
The patch did not add any new VM configuration check function,
it just port the original sanitize_vm_config() function from cpu.c
to static_checks.c with below change:
1. remove runtime rdt detection for clos check;
2. replace pr_err() from logmsg.h with printf() from stdio.h;
3. replace runtime call get_pcpu_nums() in ALL_CPUS_MASK macro
with static defined MAX_PCPU_NUM;
4. remove cpu_affinity check since pre-launched VM might share
pcpu with SOS VM;
The BOARD/SCENARIO parameter check and configuration folder check is
also moved to prebuild Makefile.
