Hi,

In linux-next I started to see: https://pastebin.com/wrDdptzh

Becasue most of the am437x boards had IRQ_TYPE_NONE for tps65218.

According to the datasheet [1] the interrult line is low active, so fix up the board
DTS files.

Interestingly the am437x-sk-evm had IRQ_TYPE_LEVEL_HIGH, which is not matching
with the datasheet.

Regards,
Peter
