bcm27xx: update distroconfig.txt for faster RPi4

Browse source 
Newer RPi 4 Rev 6 (8 GB models and recent 2 GB / 4 GB models) ship with
the so-called C0 processor which can run turbo mode at 1.8 GHz max rather
than 1.5 GHz gracefully.  Add 'arm_boost=1' to pi4 section of to enable.

Note that this setting has no effect on older chips; they continue with
their 1.5 GHz max unless users overclock them.
