ports: Make PWM duty_u16 have an upper value of 65535 across all ports.

Browse Source 
The following ports used 65536 as the upper value (100% duty cycle) and are
changed in this commit to use 65535: esp8266, mimxrt, nrf, samd.

Tested that output is high at `duty_u16(65535)` and low at `duty_u16(0)`.
Also verified that at `duty_u16(32768)` the high and low pulse have the
same length.

Partially reverts #10850, commits 9c7ad68165
and 2ac643c15b.
