mailbox: ARM_MHU_V3 should depend on ARM64

[ Upstream commit 0e4ed48292c55eeb0afab22f8930b556f17eaad2 ]

The ARM MHUv3 controller is only present on ARM64 SoCs.  Hence add a
dependency on ARM64, to prevent asking the user about this driver when
configuring a kernel for a different architecture than ARM64.
