This adds a nuttx userspace interface for hrt driver, communicating with
the actual px4 hrt driver via BOARDCTL IOCTLs
This is be used when running PX4 in NuttX protected or kernel builds

* Adds Timer15 to stm32_common, if the timer base is defined
* Adds Timer15 logic for DMA and AltFunc config on stm32h7 boards
* Adds TIM15 BDTR->MOE support in stm32_common timer init
* Adds support for TIM15 pwm channels on Matek H743 Slim
If the hardware support RESET lockout that has nArmed ANDed with VBUS
vbus_sense may drop during a param save which uses
BOARD_INDICATE_EXTERNAL_LOCKOUT_STATE to prevent external resets
while writing the params. If we are not armed and nARMRED is low
we are in such a lock out so ignore changes on VBUS_SENSE during this
time.
This adds an ioctl interface for NuttX protected build, allowing
system calls from user space to kernel for uORB, HRT and crypto

SD is on SPI3 - correct pin mapping
Fix DMA Mapping for all SPI and RX DMA on U[S]ART RX
Fix Memory MAP SRAM size
Removed unused GPIO
Used proper I2C definitions
Ensure Watchdog is configured for debugging
Fixed FLASH param definitions
Removed unedded SPI init
matek_gnss-m9n-f4:Correct Board ID and Size
Build order SJF
Added Support for F40x
Split the px4_layer into user and kernel space libraries. Add some stubs for
user-space (e.g. version) where an interface to the kernel needs to be added
Use posix-versions for cpuload.cpp and print_load.cpp for userspace; these link to nuttx internals. This functinality could be built on top of posix (e.g. procfs) interfaces

dmesg was locking the console buffer, then writing to stdout (a pipe in
the case of the MAVLink shell).
This might block, waiting for mavlink to read from the pipe. If however
mavlink tries to write to the console at that time, the lock is already
taken.
This patch avoids nested locking by using a separate buffer.
In protected build, this needs to go to user-space initialization as it
calls apps (sercon) and launches mavlink.

Add interface functions for fetching latency buckets and counters and use
those in perf_counter.cpp. This cleans up the usage of perf counters, when variables defined in hrt_drv are not referenced directly from perf.
This also enables implementing kernel-userspace interface for those for
nuttx protected/kernel build.

This fixes the case where oneshot was enabled with multi-instance pwm_out,
triggering oneshot updates too close to each other and as a result could
lead to spinning motors while disarmed.
- no longer start sercon or mavlink usb by default
- on USB connection (VBUS) monitor serial USB at low rate and start Mavlink if there's a HEARTBEAT or nshterm on 3 consecutive carriage returns
- the mavlink USB instance is automatically stopped and serdis executed if USB is disconnected
- skipping Mavlink USB (and sercon) saves a considerable amount of memory on older boards
Add common functions, implemented for nuttx, and link to architecture specific libraries
Make a separate library to wrap nuttx random number generator as "os_random".
