[PATCH 03/14] target/arm: Report correct syndrome for UNDEFINED S1E2 AT ops at EL3

[Peter Maydell]

The pseudocode for AT S1E2R and AT S1E2W says that they should be
UNDEFINED if executed at EL3 when EL2 is not enabled. We were
incorrectly using CP_ACCESS_TRAP and reporting the wrong exception
syndrome as a result. Use CP_ACCESS_TRAP_UNCATEGORIZED.

translation ops")
