f9299c4461 Make timer definition in pin files for STM32 possible (#12874)
RemRam needs to redefine a particular timer to work correctly. The HAL did foresee this possibility and checks if the timer was already defined for either the stepper or temperature timer.

Prior to this commit the header file for the timers couldn't see those definitions in the pin file, but this commit will fix this.

Tested on an actual hardware to verify. (It wouldn't boot without it.)

4975b13b74 Fix problems with LPC1768 EEPROM flash emulation (#12503)
* Remove duplicate calls to PrepareSector

Some flash memory API calls require that a call to `PrepareSector` is done before use. However this call is already made by the LPC1768 framework so the calls in this code are not required.

* Ensure correct alignment of RAM buffer

The LPC176X flash API requires that the RAM buffer used for write operations must be word-aligned. This change ensures that this is the case.

5a4fd8e0a6 Fix access to the DWT peripheral for STM32 HAL (#12434)
Access to the DWT peripheral for the `CYCCNT` register needs to happen before `main()`. The code needs to be called after the setup of the system clocks, so the right place is between the `premain()` and `main()` function of the STM32 Arduino core.

This patch moves the DWT access code to a new function, which is then placed between `premain()` and `main()`.

- Fix an error in the return value of `sd_mmc_spi_read_capacity` which was causing the host OS to read beyond the last sector in the card.
- Clean up the USB flashdrive code and add better debugging.

870bfd08f5 usb and sdcard sharing improvements
* Add traceback after watchdog timeout

Add the cpability to perform a traceback following a watchdog timeout.

* Enhanced hardware SPI

Allow use of either SSP0 or SSP1.
Ensure that no data is left in I/O buffers after calls to enable sharing of SSP hardware.

* Make flash emulation of eeprom the default

Make use of flash for eeprom storage the default. This means that usage of eeprom will not cause USB drive mount/unmount operations.

* Allow sharing of SD card

SD card I/O operations from the USB stack take place in idle loop, rather than at interrupt time. Allowing sharing of the SPI bus.

New configuration options to allow usage of the SD card to be specified.

* Fix problem with hardware SPI pins
