ports: Make PWM duty_u16 have an upper value of 65535 across all ports.
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 9c7ad68165bcd224c94ca6d8f172362cf8000d99
and 2ac643c15bec8c88ece0e944ce58f36d02dfd2dd.
