ARM/dt: hammerhead: Reduce minimum panel brightness

Default minimum brightness is a tad too high, this change makes reading
in a dark environment much more enjoyable. A value of 3 is still within
the valid range (see lm3630 blmap).

Thanks @neobuddy89 never think it's has this set, as i was lazzy to look for it.
BT: restored net/bluetooth/hci_core.c to STOCK. READ MORE.

Since BT is active on suspend, i should not cancel_work

Seems like i am having kernel stuck after long BT activity.
but without any BT stream.
FORCE FAST CHARGE: v2.3 added more checks, and code style.

*New checks to thermal mitigation functions and corrected code style.
*Removed updating charging scenario when no charger connected. no point to do so.
