David Lin 0f959efa6c vibrator: add calibration data loading support ...

This patch adds the support of loading a calibration file and write it
back to the drv2624 kernel driver. The calibration file contains the
BEMF, GAIN and COMP numbers generated using the auto-calibration feature
of the drv2624 driver IC. The file also contains the per-device resonant
frequency number.

Test: calibrate the device and read back the values from kernel
