Is your enhancement proposal related to a problem? Please describe.
The CC13xx/CC26xx gpio driver does not support setting the drive strength of an IO pin. It is instead fixed at 2mA. IO pins also support 4mA, and some support 8mA.
Describe the solution you'd like
Support the GPIO_DS_ALT_LOW and GPIO_DS_ALT_HIGH gpio flags.
