Previously when issuing a load_config, each pwm channel
was stopped in its tracks and waited for an external sync,
if that was active, or load_config release.
The desired behaviour is to wait for the pwm channels to finish
their events from the current period, before a new aligned start.
Also, the first positive edge of each pulse was initiated only
in the second pwm channel period.
This niche behaviours have not affected any functionality in the
long term alignments for current setups.

When leaving the offset equal to zero for a pwm
channel. That pwm channel was not waiting for all
channels to get in sync after a load config.

Fix offset for pwms with different periods.
The previous version was using an offset scheme based on pwm counter_0.
By using a separate offset counter the user will not be constrained by
pwm_0 period in regards with the offset of other pulses. In this version
offset 0 is used to delay pwm 0 in regards to the offset counter.
The offset counter will start after the load_config signal is asserted
and all active pwm counters finish the previous cycle or by a software
reset.
The software reset should also be used when using external_sync.
