In commit a96edb687e we set the cpu_exec_halt field of the
TCGCPUOps arm_tcg_ops to arm_cpu_exec_halt(), but we left the
arm_v7m_tcg_ops struct unchanged. That isn't wrong, because for
M-profile FEAT_WFxT doesn't exist and the default handling for "no
cpu_exec_halt method" is correct, but it's perhaps a little
confusing. We would also like to make setting the cpu_exec_halt
method mandatory.
Initialize arm_v7m_tcg_ops cpu_exec_halt to the same function we use
for A-profile. (On M-profile we never set up the wfxt timer so there
is no change in behaviour here.)
