Julien Massot 0bb0056abc target:armv8: aarch32 do not try to restore same EL ...

While debugging a Cortex-R52 OpenOCD fail to restore context
on line
retval = dpm->instr_write_data_r0(dpm,
		ARMV8_MSR_GP_xPSR_T1(1, 0, 15), cpsr);

which trigger this exception:

aarch64.c:1206 aarch64_restore_context(): r8a779a0.r52
armv8_dpm.c:560 armv8_dpm_modeswitch(): restoring mode, cpsr = 0x0000011f
1262753 armv8_dpm.c:598 armv8_dpm_modeswitch(): target_el = 1, last_el = 1
armv8_dpm.c:611 armv8_dpm_modeswitch(): SPSR = 0x0000011f
armv8_dpm.c:260 dpmv8_exec_opcode(): Opcode 0x8f00f390, DSCR.ERR=1, DSCR.EL=1

and finally OpenOCD doesn't succeed to restore the processor.

This check 'dpm->last_el != target_el' exist for aarch64,
so might be correct for aarch32 too.
