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

The medium and strong now shares the same strength to provide a stronger
default feedback.
