Backport the Microchip EMC2305 driver changes up to current linux-next.
These are required in order to actually be able to use the driver with
DTS support to drive fans as cooling devices.
Replace the bcm27xx RPi patch with the one from RPi kernel 7.0 that was
already adapted to all of these backports.
