Add a new HAVE_LIMITED_CODE_SIZE symbol that enables a menu to select
optional features. This symbol is enabled on chips with small build
sizes.
Replace the HAVE_GPIO_BITBANGING with four new symbols:
WANT_GPIO_BITBANGING, WANT_DISPLAYS, WANT_SENSORS, WANT_SOFTWARE_SPI,
and WANT_SOFTWARE_I2C. This allows users a little more flexibility
when selecting features they need.

Check for the build symbol prior to calling bootloader_request().
Enable the build symbol on rp2040, atsam, and atsamd chips.
This also enables serial bootloader requsts on rp2040, atsam, and
atsamd.

Rename this board API function to a more generic name. This is in
preparation for calling the function from the canbus code.

Accidentally introduced in 8049243221,
renders the AFE non-functional on SAME70. Should have had little impact
on SAM4E.

Multiplying the desired bitrate by 4 results in half the
desired period and thus twice the desired bitrate.

This clock is only needed for low-power operation mode,
and wasn't correctly configured anyway (should be 48MHz).

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 floating point unit must be enabled in order to use it and Klipper
does not currently implement that. Newer versions of gcc may spill
registers to the floating point unit causing failures.

Add a new build definition to note micro-controllers that have strict
timing. The Linux mcu code does not have strict timing - all other
targets currently do.

The main() function has a special meaning to gcc and using it can
result in different code generation. Use armcm_main() to avoid that.
Also, invoke SystemInit() from the board specific armcm_main() code.
This gives the board code more control over board initialization.

The ADC pins (on at least the sam3x8e) need to be configured in input
mode with the internal pullups disabled in order to get accurate ADC
readings.

Make it clear that the name of the constant being defined is a string.
When the value being defined is also a string, use a new
DECL_CONSTANT_STR() macro.

It's rare to use all of a target's prerequisites in a recipe - replace

The sram matrix configuration is, bizarrely, configured with a slow

access. Set the matrix sram controller to improve the performance.
