Currently ept_pages_info[] is initialized with first element only that force
VM of id 0 using SOS EPT pages. This is incorrect for logical partition and
hybrid scenario. Considering SOS_RAM_SIZE and UOS_RAM_SIZE are configured
separately, we should use different ept pages accordingly.
So, the PRE_VM_NUM/SOS_VM_NUM and MAX_POST_VM_NUM macros are introduced to
resolve this issue. The macros would be generated by acrn-config tool when
user configure ACRN for their specific scenario.
One more thing, that when UOS_RAM_SIZE is less then 2GB, the EPT address
range should be (4G + PLATFORM_HI_MMIO_SIZE).

This patch overwrites the idle driver of service OS for industry, sdc,
sdc2 scenarios. HLT will be used as the default idle action.

Add this vcpu_affinity[] for each VM to indicate the assignment policy.
With it, pcpu_bitmap is not needed, so remove it from vm_config.
Instead, vcpu_affinity is a must for each VM.
This patch also add some sanitize check of vcpu_affinity[]. Here are
some rules:
1) only one bit can be set for each vcpu_affinity of vcpu.
2) two vcpus in same VM cannot be set with same vcpu_affinity.
3) vcpu_affinity cannot be set to the pcpu which used by pre-launched VM.
v4: config SDC with CONFIG_MAX_KATA_VM_NUM
v5: config SDC with CONFIG_MAX_PCPU_NUM

Per community requirement;up to three post-launched VM might be
needed for some automotive SDC system, so add SDC2 scenario to
satisfy this requirement.
