Implement initial support for MKS Robin (STM32F103ZET6) board.
Custom build script is used to generate encrypted firmware compatible with original MSK Robin bootloader (i.e. safe firmware update from SD card and possibility to go back to original close-source firmware).
* 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.
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()`.
- Remove `print_job_timer.stop()` from `disable_all_heaters`
- Call `print_job_timer.stop()` for relevant `disable_all_heaters()`.
- Split up `kill()` for watchdog interrupt safety
- 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.
* 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

Some STM32-based boards may use multiplexed JTAG pins as IO. Up to now the `DISABLE_JTAG` option (defined in pins files) was only supported for AT90-based boards. This commit generalizes the code and adds support for boards based on STM32F1 and STM32F4.
The `binary.h` file required by `lcd/dogm/dogm_bitmaps.h` is not present in stm32duino environment. Binary macros are defined in `bit_constants.h` in stm32duino framework.
- Clean up the API to use a `static` class instance to adhere to Marlin convention
- Add `const` position data access for read/write
- Add Storage capacity to the interface
The current Marlin implementation relies on a timer interrupt to start the ADC conversion and read it. However in some circumstances the interrupt can be delayed resulting in insufficient time being available for the ADC conversion. This results in a bad reading and false temperature fluctuations. These changes make sure that the conversion is complete (by checking the ADC hardware via the HAL) before reading a value.
