NRF_52840: Fix us ticker counter size 

It has been noticed that there is a problem with us ticker on NRF_52840 board after 32 bit counter has been used for us ticker on NRF52 family boards.
Currently NRF52 symbol is defined only for MCU_NRF52832 (not for MCU_NRF52840) and based on this symbol 16 or 32 bit counter is selected (16 bit for NRF51 family and 32 for NRF52 family).
Since MCU_NRF52840 defines NRF52840_XXAA and provides 32 bit counters, 32 bit counter should be selected also when NRF52840_XXAA symbol is defined.
