x86, as some of the common sub-ops are not supported on Arm. The Arm
specific handler filetrs out the not supported sub-ops and then calls

the common handler. This leads to the weird call hierarchy:
do_arm_vcpu_op()
do_vcpu_op()
arch_do_vcpu_op()
Clean this up by renaming do_vcpu_op() to common_vcpu_op() and
arch_do_vcpu_op() in each architecture to do_vcpu_op(). This way one
of above calls can be avoided without restricting any potential
future use of common sub-ops for Arm.
Additionally the single user of HYPERCALL_ARM() can be modified and
HYPERCALL_ARM() can be removed.
