KVM: arm64: Introduce KVM_REG_ARM_VENDOR_HYP_BMAP_2
The vendor_hyp_bmap bitmap holds the information about the Vendor Hyp services available to the user space and can be get/set using {G, S}ET_ONE_REG interfaces. This is done using the pseudo-firmware bitmap register KVM_REG_ARM_VENDOR_HYP_BMAP. At present, this bitmap is a 64 bit one and since the function numbers for newly added DISCOVER_IPML_* hypercalls are 64-65, introduce another pseudo-firmware bitmap register KVM_REG_ARM_VENDOR_HYP_BMAP_2.
