firmware: smccc: Support both smc and hvc conduits for getting hyp UUID
When Linux is running as the root partition under Microsoft Hypervisor
(MSHV) a.k.a Hyper-V, smc is used as the conduit for smc calls.
Extend arm_smccc_hypervisor_has_uuid() to support this usecase. Use
arm_smccc_1_1_invoke to retrieve and use the appropriate conduit instead
of supporting only hvc.
Boot tested on MSHV guest, MSHV root & KVM guest.
