This patch moves the device playback mode configuration from off() to
on() to avoid the unnecessarily switching from rtp to waveform mode for
consecutive waveform playbacks.

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

When outputting uint8_t / char to sysfs using ofstream it gets to
stringified to a character instead of string. For example, writing 127
would get converted to "\x7F\0a" in text while sysfs generally only
accept input in dec "127" or "0x7f" in hex format. This patch changes
the rtp_input type to uint32_t instead.

This patch updates the click waveform to use 6 ms full amplitude as well
as switching to open-loop mode for any duration that's less than 20 ms.
The medium and strong now shares the same strength to provide a stronger
default feedback.
