Peter Maydell fbe5ac5671 target/arm: take HSTR traps of cp15 accesses to EL2, not EL1 
The HSTR_EL2 register allows the hypervisor to trap AArch32 EL1 and
EL0 accesses to cp15 registers.  We incorrectly implemented this so
they trap to EL1 when we detect the need for a HSTR trap at code
generation time.  (The check in access_check_cp_reg() which we do at
runtime to catch traps from EL0 is correctly routing them to EL2.)

Use the correct target EL when generating the code to take the trap.
