- `gpio_ll_toggle()` now is race-free
- avoid using a look up table but branch to the two different registers
in the `gpio_ll*()` functions
- in most cases the GPIO port is a compile time constant and the
dead branch is eliminated by the optimizer, making this vastly
more efficient
- some MCUs do only have a single port, in which case
`GPIO_PORT_NUM(port)` is known to return `0` even if `port` is
not known, resulting in one of the branch being eliminated as
dead branch no matter what
- in case it really is unknown at compile time which port to work
on, the branch can still be implemented efficiently by the
compiler e.g. using a conditional move; likely more efficient
than fetching a value from the look up table.
