robert-hh 4160ec087b samd/mcu: Set the SAMD21 us-counter to 2 MHz for better resolution.
It turned out that the result of calling ticks_us() was always either odd
or even, depending on some internal state during boot.  So the us-counter
was set to a 2 MHz input and the result shifted by 1.  The counting period
is still long enough, since internally a (now) 63 bit value is used for us.
