Driver changes for omaps for v6.6

Driver changes for ti-sysc interconnect target module driver and for
l3 interconnect error handler. The ti-sysc driver changes just enable
using it for 64-bit systems like TI am62 that have wake-up capability
for the wkup domain devices. The l3 error handling improves the code
to show the error source if an unrecoverable timeout error occurs.
