Since the Onshot<->PWM mode is changed based on rate. The
this signale the higher layers that the operation is invalid
test case:
fmu task mode_pwm2cap2
pwm oneshot -m 0xf -g 0 -d /dev/pwm_output0
should fail, because all the channels in the group are
not in the same mode.
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.
1) Define IOTimerChanMode_OneShot
2) Added detailed commnent on .clock_freq and how it is used
3) Added single additional API point in support of Onshot mode
io_timer_trigger - That trigger all timer's channels in Oneshot
mode to fire the oneshots with updated values.
1) Validate timer paramater before using it.
2) Allow rate of 0 to enter Oneshot mode
At first blush this seamed like a hack, but at Mark
pointed out to me, Onshot PWM does not have a rate
So this is a realy a clever and beautiful simplification
on his part!
3) Exposes up_pwm_update that runs io_timer_trigger
Which trigger all timer's channels in Oneshot mode to
fire the oneshots with updated values.
The fmu now support the commandline option to be run as a task
or off a work queue.

stm32f7: stm32_allocateheap: allow use DTCM memory for heap
STM32F7 has up to 128KiB of DTCM memory that is currently left unused.
This patch adds DTCM to main heap if CONFIG_STM32F7_DTCMEXCLUDE is not enabled.
* px4fmu-v5_default:Enable inclusion of the DTCM in the heap
CONFIG_MM_REGIONS=3 adds the DTCM region to the heap.

sem_holder: Fixes improper restoration of base_priority
in the case of CONFIG_SEM_PREALLOCHOLDERS=0
Original code did not take into accout that 2 holder are needed
and failed silently when a slot could not be allocated
The call to sem_restorebaseprio_task context switches in the
sem_foreachholder(sem, sem_restoreholderprioB, stcb); call
prior to releasing the holder. So the running task is left
as a holder as is the started task. Leaving both slots filled
Thus failing to perforem the boost/or restoration on the
correct tcb.
This PR fixes this by releasing the running task slot prior
to reprioritization that can lead to the context switch.
To faclitate this, the interface to sem_restorebaseprio
needed to take the tcb from the holder prior to the
holder being freed. In the failure case where sched_verifytcb
fails it added the overhead of looking up the holder.
There is also the additional thunking on the foreach to
get from holer to holder->tcb.

Improper rounding in redundant stack coloring
routines could overwriting the TOS+1 and BOS-1
depending on the value of CONFIG_ARCH_INTERRUPTSTACK
This applies the compelet upstream set of fixes from
David Cabecinhas <david.cab+bitbucket@gmail.com>
Improper rouding in redundant stack coloring
routines was overwriting the TOS+1 and BOS-1
The legacy OABI 4 byte stack alingment was removed
Only the EABI 8 byte alinement is supported
The redundant interrupt stack coloring. up_initalize
had the correct implemantation (last verson of patch)
and the redundant version in the
arch/arm/src/stmxxx/stmxx_irq.c was calculating the size
wrong.
This is fixed by rounding up CONFIG_ARCH_INTERRUPTSTACK
by 4 bytes when allocated and alining on a 8 byte boundry
nuttx-patches/workarround_for_flash_data_cache_corruption.patch was
patching a file patched in nuttx-patches/wip_inflight_to_upstream.patch
The changes in workarround_for_flash_data_cache_corruption.patch
will be submitted upstream once refactored (upstream coding style
compliant and moved to correct location)
