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.
