nrf52840: missing `APPROTECT` and the `HwDisable` value for `UICR.APPROTECT` #17

These are important, because without access to these peripherals, revision 3 chips will enter a protected state that blocks the hardware debugger from accessing them on reset.

It appears this was added to the nrf52840 product specification in April 2021

Both the APPROTECT peripheral and the HwDisabled value for the UICR.APPROTECT register are present in the SVDs distributed with the nRF5 SDK v17.1.0 or nRF MDK v8.57.0.
