mb/google/brox: Fix booting to kernel without battery
When battery is disconnected and only adaptor is connected higher PL2
power draw causes cpu brown out and system does not boot to kernel. To
avoid this set Boot frequency UPD to 1. Reduce PL4 value to overcome
power spikes from SoC during boot. Remove Psys implementation as it
impacts active state platform performance.
BUG=b:335046538,b:329722827
BRANCH=None
TEST=Able to successfully boot on 3 different Brox proto2 SKU1
and SKU2 boards with 65W, 45W and 30W adaptors for 3
iterations of cold boot.
