1) Updated copyright
2) Defined BOARD overrideable BOARD_PWM_FREQ and BOARD_ONSHOT_FREQ
Not recogmended but allow experimentation
3) Solved the support for BOARD_PWM_DRIVE_ACTIVE_LOW using
the Polarity control bits as apposed to the negation of
the ARR.
4) Added a cache for getting a timers channels. This is static
and benifits from the qucik response.
5) Added a function to realocate all channes in a given timer
from one mode to another.
6) Removed the frequecy table in favor of the intended use of the
channel mode set. At it is the way to determine the mode of a
channel. Or in onshot's case a timers's complete set channels.
7) Added 2 lowlevel mode changing functions:
io_timer_set_oneshot_mode and io_timer_set_PWM_mode
that encapsalate the changes in mode to one place
in the code.
8) Added io_timer_trigger (the up_pwm_update) with low
latancy timer to time in updating.
9) io_timer_set_rate - use sets to enforce all or none
rules for switching PWM<->OneShot.
Onshot is entered using the very approriate rate of 0.
Only deltas will change the HW state.
