KVM: x86: Support for disabling quirks
Introducing KVM_CAP_DISABLE_QUIRKS for disabling x86 quirks that were previous created in order to overcome QEMU issues. Those issue were mostly result of invalid VM BIOS. Currently there are two quirks that can be disabled: 1. KVM_QUIRK_LINT0_REENABLED - LINT0 was enabled after boot 2. KVM_QUIRK_CD_NW_CLEARED - CD and NW are cleared after boot These two issues are already resolved in recent releases of QEMU, and would therefore be disabled by QEMU.
