Ulaş Sertan Kemeç 986394a56d arch/arm/am67: Add eCAP APWM lower-half driver.
Adds a PWM lower-half using the eCAP modules in APWM mode as single-channel
generators rather than capture units.

start() reprograms the time base only when the frequency changes, so a
duty-only update does not stop or zero a live counter.

t3-gem-o1 registers /dev/ecap1 and /dev/ecap2; output pad selection is left to
the board, as the candidates collide with I2C0.

Verified on t3-gem-o1: examples/pwm runs a 1 kHz, 50% duty train on both
instances and accepts a duty-only change (25% then 75%).  The output pins have
not been measured on copper, as no pad is assigned to them on this board.
