Review Comment:
If the problem is related to the board then we have to introduce a delay
(but implemented with `up_udelay()`) configurable with Kconfig (in
`arch/nrf52/Kconfig`), but disabled by default. We cannot make the architecture
code dependent on the board implementation. Then every board that needs a fix
will have to set the delay in board defconfigs.
