[PATCH v2 01/13] thermal/drivers/mediatek/lvts_thermal: retrieve all calibration bytes

From: Nicolas Pitre <npitre at baylibre.com>

Calibration values are 24-bit wide. Those values so far appear to span
only 16 bits but let's not push our luck.

Found while looking at the original Mediatek driver code.
