coresight: trbe: Add ISB after TRBLIMITR write

DEN0154 states that hardware will be allowed to ignore writes to TRB*
registers while the trace buffer is enabled. Add an ISB to ensure that
it's disabled before clearing the other registers.

This is purely defensive because it's expected that arm_trbe_disable()
would be called before teardown which has the required ISB.
