Temperature readings on the MT7988 are severely abnormal and inaccurate
on some devices when using the default commands.
Patches to fix this have been posted and merged for Linux 6.17, however,
missing a Fixes:-tag they have not been picked into the Linux 6.12 stable
tree which already comes with the driver support for MT7988 and hence
suffers from this problem.
All 3 commits apply cleanly on top of linux-6.12.y, so cherry-pick them
now, adding the appropriate Fixes:-tag.

  thermal/drivers/mediatek/lvts_thermal: Change lvts commands array to
    static const
  thermal/drivers/mediatek/lvts_thermal: Add lvts commands and their
    sizes to driver data
  thermal/drivers/mediatek/lvts_thermal: Add mt7988 lvts commands

[ Upstream commit 685a755089f95b7e205c0202567d9a647f9de096 ]

These commands are necessary to avoid severely abnormal and inaccurate
temperature readings that are caused by using the default commands.
