Subject: [PATCH] HV: add generic board config

hypervisor/arch/x86/configs/($CONFIG_BOARD) will store Board specific configs,
add a generic folder to store configs for generic boards that they can share
one build binary with minimal and common features in some scenarios like SDC.

Please be aware that BDF of pci devices are different on each board, so one
binary for LOGICAL_PARTITION scenario is not supported.

Tracked-On: #2291
