From: Will Deacon <redacted>

Sparse kicks up about a type mismatch for kvm_target_cpu:

arch/arm64/kvm/guest.c:271:25: error: symbol 'kvm_target_cpu' redeclared with different type (originally declared at ./arch/arm64/include/asm/kvm_host.h:45) - different modifiers

so fix this by adding the missing const attribute to the function
declaration.
