brcm_patchram_plus restart fails to upload firmware #6

Bluetooth chip is not ready for firmware on restart of service, only after reboot of board. Causing upload to go into a loop of failed attempts.

I believe pulling BT_RST_N low, will reset the BT chip allowing firmware to be uploaded. This line is hooked to TCLK/GPB4 which will need to be accessed.

hciattach was blocking /dev/ttySAC1 Issue fixed with PID number tracking and using it to kill the hciattach process on stoppage.
