Devicetree bindings: st,stm32wb-ble-rf.yaml: fix BD Address error

HCI RESET done in common_init() function in
the zephyr\subsys\bluetooth\host\hci_core.c file erase settings done
before in the zephyr\drivers\bluetooth\hci\ipm_stm32wb.c
in the bt_ipm_setup() function.
HCI RESET can be avoided by set a default "no-reset"
in the zephyr\dts\bindings\bluetooth\st,stm32wb-ble-rf.yaml
