kvm: support using KVM_MEM_READONLY flag for regions
For readonly memory regions and rom devices in romd_mode,
we make use of the KVM_MEM_READONLY. A slot that uses
KVM_MEM_READONLY can be read from and code can execute from the
region, but writes will exit to qemu.
After reverting this commit, VM can boot normally.
Any information I should provide?
