target/arm: Report correct syndrome for UNDEFINED CNTPS_*_EL1 from EL2 and NS EL1

target/arm: Report correct syndrome for UNDEFINED CNTPS_*_EL1 from EL2 and NS EL1

The access pseudocode for the CNTPS_TVAL_EL1, CNTPS_CTL_EL1 and
CNTPS_CVAL_EL1 secure timer registers says that they are UNDEFINED
from EL2 or NS EL1.  We incorrectly return CP_ACCESS_TRAP from the
access function in these cases, which means that we report the wrong
syndrome value to the target EL.

Use CP_ACCESS_TRAP_UNCATEGORIZED, which reports the correct syndrome
value for an UNDEFINED instruction.
