From: Frank Wunderlich <frank-w@xxxxxxxxxxxxxxx>

On mt7987 we see a crash due to missing ops entry.

[ 1.518540] Internal error: Oops: 0000000096000005 [#1] SMP

[ 1.564481] pc : lvts_get_temp+0x84/0xc4

[ 1.656502] __thermal_zone_device_update+0x9c/0x52c

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