modules: hal: ti: fix timer integration issues

Updates the TI hal modules to include the following fixes in Zephyr's
ClockP API implementation:
 * The unused stubs.h header was removed.
 * The ClockP implementation contained some cruft due to an incomplete
   migration from the ms based to the tick based kernel timer API.
 * The ClockP implementation assumed timeouts and periods to be given in
   ms although TI's API always expected ticks.
 * A fix for a major conversion bug in TI's own usage of the ClockP API
   throughout the SimpleLink framework is included.
