Binbin Wu 245a732055 hv: sgx: add basic support to init sgx resource for vm ...

Get the platform EPC resource and partiton the EPC resource for VMs
according to VM configurations.
Don't support sgx capability in SOS VM.
init_sgx is called during platform bsp initialization.
If init_sgx() fails, consider it as configuration error, panic the system.
init_sgx() fails if one of the following happens when at least one VM requests
EPC resource if no enough EPC resource for all VMs.
No further check if sgx is not supported by platform or not opted-in in BIOS,
just disable SGX support for VMs.
