soc: fsl: cpm1: qmc: Fix assigned timeslot masks

The assigned timeslot masks are 64bit values.
In case of 64 timeslots the code uses (1 << 64) which is undefined on a
64bit value. On the PowerPC architecture, this lead to an incorrect
result as (1 << 64) produces the same result as (1 << 0).

Fix the masks values taking care of the 64 timeslots case.
