The gpio_peripheral() code is the same in stm32f0.c, stm32f4.c, and
stm32h7.c. Move that function to a new gpioperiph.c file to avoid
code duplication.

Don't go above 400Mhz as otherwise it causes 32bit rollover issues.

seconds.)

Add an optimized step function for drivers that support stepping on
both rising and falling edges of the step pin. Enable this
optimization on 32bit ARM micro-controllers. Automatically detect
this capability in the host code and enable on TMC drivers running in
SPI/UART mode.

The previous OSPEEDR value of 0x2 was copied from the stm32f4.c code,
but the stm32f0 interprets that value the same as 0x0 - which is "low"
speed. Change the OSPEEDR value to "medium" speed so that it matches
the configuration of stm32f1 chips.

This change has been expanded to include all STM32F4 processors, since they share a common TIMER mapping with some processors just not having all of the timers and pins.

This commit contains a configuration for the Anycubic Vyper printer from 2021.
It uses a clone of the STM32F103 chip named GD32F103.
There are 2 Mainboard versions out there v0.0.5 and v0.0.6, this config has
been tested with the v0.0.6 only. It should probably work for v0.0.5 as well
since there are no different changes in the Anycubic Marlin firmware.
The LCD is not supported yet (might work, but didn't try yet).

The F405, F407, and F429 chips are in the same series and almost all
code definitions should apply to all chips in that series. Implement
the alias and fix defintions in adc.c and Kconfig that were only
applying to a subset of that series.

Separate out the high-level command processing logic from the

The spec states that the TX fifo is transmitted in chronological order
if the TXFP bit is set, but it's unclear if the software needs to fill
the tx fifo in a particular order to obtain that result. Use the TSR
CODE bit field to fill the TX fifo in the order that the hardware
reports as next.

Prefer explicitly setting the hardware registers and avoid using C
read and modify instructions where possible. This avoids race
conditions where an interrupt or hardware change could cause subtle
corruption of the register state.
