bcm27xx: enable THERMAL_WRITABLE_TRIPS on bcm2710 and bcm2711

The PoE hat supported on the RPi 3B+ and 4B comes with a rather
loud fan, tripped in two steps by the brcmstb_thermal
thermal_zone driver.  Enabling writable trip points allow
users to adjust the fan trip points according to their
preferred temp/noise ratio.

This setting is enabled on most other targets with similar
thermal_zone controlled cooling devices.
