HID: pidff: Rescale time values to match field units

[ Upstream commit 8713107221a8ce4021ec5fa12bb50ecc8165cf08 ]

PID devices can use different exponents for time fields, while Linux
Force Feedback API only supports miliseconds.

Read the exponent of a given time field and scale its value accordingly.

Changes in v7:
- Rescale all time fields, not only period

changes in v9:
- Properly assign fade_lenght, not attack_length to PID_FADE_TIME
