mb/lenovo: Unify thermal threshold handling

Unify thermal handling across Lenovo boards (except g505, which is
different). Namely, do the following:

* Move thermal levels from acpi_tables to thermal.h (and create if
  necessary).
* Don't use board-specific ifdef guards.
* Set thermal levels using dedicated acpi_update_thermal_table function
  as almost all Lenovo boards do.
* Update list of authors in comments. Merge all author's entries.
* Minor whitespace and formatting.

This makes diff -ruw between the Lenovo boards smaller.
