Fixed three bugs in the RP23XX (RISC-V) PWM driver, mirroring the fix
previously applied to the ARM variant:
* setup_period: The previous divisor calculation used integer arithmetic
that caused overflow and loss of precision. The divider is now computed
as a 16-bit fixed-point value (div16) using 64-bit arithmetic, and
clamped to the valid hardware range (0x10 to 0xFFF).
* setup_pulse: The compare value was incorrectly scaled by TOP instead
of 65535, producing wrong duty cycles. The formula is now corrected
to ((duty * (top + 1)) / 65535) with an overflow guard.
* pwm_start: The driver was not updated as part of the breaking change
introduced in commit
