overlays: rpi-poe-plus: Improve the cooling levels

pelwell · popcornmix · commit 1fdfe3352f50 · 2021-09-08T14:23:16.000+01:00
The PoE HAT cooling levels are not well suited for the PoE+ HAT - the fan fails to come on until the temperature reaches the third trip point (50C). Give the rpi-poe-plus overlay a different set of cooling levels - 0 32 64 128 255, as suggested by @chris-kai-in. See: raspberrypi/firmware#1607 Signed-off-by: Phil Elwell <phil@raspberrypi.com>
