Subject: [PATCH] Input: elants_i2c - fix typo for an attribute to show calibration count

Fixed typo for command from 0xE0 to 0xD0.

commit cf520c643012 ("Input: elants_i2c - provide an attribute
to show calibration count")

There is an non-touch case by non-calibration after update firmware.
Elan could know calibrate or not by calibration count.
The value of '0xffff' means we didn't calibrate after update firmware.
If calibrate success, it will plus one and change to '0x0000'.
