The SRS instruction is: * UNDEFINED in Hyp mode * UNPREDICTABLE in User or System mode * UNPREDICTABLE if the specified mode isn't accessible * trapped to EL3 if EL3 is AArch64 and we are at Secure EL1 Clean up the code to handle all these cases cleanly, including picking UNDEF as our choice of UNPREDICTABLE behaviour rather blindly trusting the mode field passed in the instruction. As part of this, move the check for IS_USER into gen_srs() itself rather than having it done by the caller. The exception is that we don't UNDEF for calls from System mode, which need a runtime check. This will be dealt with in the following commits.
