Peter Maydell 034bb45ac1 target/arm: Disable HSTR_EL2 traps if EL2 is not enabled 
The HSTR_EL2 register is not supposed to have an effect unless EL2 is
enabled in the current security state.  We weren't checking for this,
which meant that if the guest set up the HSTR_EL2 register we would
incorrectly trap even for accesses from Secure EL0 and EL1.

Add the missing checks. (Other places where we look at HSTR_EL2
for the not-in-v8A bits TTEE and TJDBX are already checking that
we are in NS EL0 or EL1, so there we alredy know EL2 is enabled.)
