commit 6a35e8f4ee68923006bba404f1f2471038b1039c

target/arm: do not use cc->do_interrupt for KVM directly
cc->do_interrupt is a TCG callback used in accel/tcg only,
call instead directly the arm_cpu_do_interrupt for the
injection of exeptions from KVM, so that
do_interrupt can be exported to TCG-only operations in
the CPUClass.
