[PATCH v3 3/9] target/arm: Make CNTPS_* UNDEF from Secure EL1 when Secure EL2 is enabled

[Peter Maydell]

When we added Secure EL2 support, we missed that this needs an update
to the access code for the EL3 physical timer registers.  These are
supposed to UNDEF from Secure EL1 when Secure EL2 is enabled.
