From: João Paulo Gonçalves <joao.goncal...@toradex.com>
While TI AM62P supports up to 125°C junction temperature, Tj, for
industrial and automotive parts, Toradex Verdin-AM62P hardware lifetime
guarantees consider a 105°C Tj. Fixup the device tree temperature
critical trip points to match the hardware specifications. The
implementation ensures the architecture code will not overwrite the
board specific changes by enabling CONFIG_OF_BOARD_SETUP_EXTENDED for
the Verdin-AM62P.
