Jeff Kubascik 95e39f60be target/arm: adjust program counter for wfi exception in AArch32 
The wfi instruction can be configured to be trapped by a higher exception
level, such as the EL2 hypervisor. When the instruction is trapped, the
program counter should contain the address of the wfi instruction that
caused the exception. The program counter is adjusted for this in the wfi op
helper function.

However, this correction is done to env->pc, which only applies to AArch64
mode. For AArch32, the program counter is stored in env->regs[15]. This
adds an if-else statement to modify the correct program counter location
based on the the current CPU mode.

Backports commit 855532912b0e1bf803ae393e5b0c7e80948cd6a4 from qemu
