[ Upstream commit 44f416879a442600b006ef7dec3a6dc98bcf59c6 ]

We have gpio_86 wired internally to the bandgap thermal shutdown
interrupt on 4430 like we have it on 4460 according to the TRM.
This can be found easily by searching for TSHUT.

For some reason the thermal shutdown interrupt was never added
for 4430, let's add it. I believe this is needed for the thermal
shutdown interrupt handler ti_bandgap_tshut_irq_handler() to call
orderly_poweroff().
