/* TRM ERRATA: Timer 3 & 6 default parent (TCLKIN) may not be always
 *    physically present, in such a case HWMOD enabling of
 *    clock would be failure with default parent. And timer
 *    probe thinks clock is already enabled, this leads to
 *    crash upon accessing timer 3 & 6 registers in probe.
 *    Fix by setting parent of both these timers to master
 *    oscillator clock.
