pwm: imx27: Fix variable truncation in .apply()
Fix a variable truncation when calculating period in microseconds as
part of the solution for the ERR051198 in .apply() callback.
Example scenario:
- Period of 3us (PWMPR = 196 and prescaler = 1)
- Expected value in tmp: 198000000000 (NSEC_PER_SEC * (196 + 2) * 1)
- Actual value is 431504384 (truncation to u32)
