dt-bindings: net: ti,cc1352p7: Add bootloader-backdoor-gpios
bootloader-backdoor-gpio (along with reset-gpio) is used to enable
bootloader backdoor for flashing new firmware.
The pin and pin level to enable bootloader backdoor is configured using
the following CCFG variables in cc1352p7:
- SET_CCFG_BL_CONFIG_BL_PIN_NO
- SET_CCFG_BL_CONFIG_BL_LEVEL
