Commit a4c40559499f ("thermal/drivers/mediatek/lvts: Add platform ops to
support alternative conversion logic") added new ops field which causes
crash on mt7987.

Add the new ops member added in 7.0-rc1 for mt7987 too.

Commit 6931d597c5ef ("thermal/drivers/mediatek/lvts: Make number of
calibration offsets configurable") introduced field num_cal_offsets
in lvts_data. Add this for mt7987 too.
