'brew' apparently introduced an incompatible change, where even
"--force" does not actually make the commands available in the default path.
Also switch to a numbered macos release instead of "latest", though this
did not save us from breaking changes in brew or other preinstalled sw.
Previously, we were using v6.1.1 which worked, but was unsupported.
v7.0.1 is the first version of s140 that supports the nRF52833.

When allocate_display_bus_or_raise was factored out, the assignment
of the bus's Python type was lost. Restore it.
This would have affected displays of any type other than RGBMatrix, when
they were created dynamically. Boards with displays configured in flash
were unaffected.
Closes: #2792
Allow for setting various softradio memory settings as part of a
board in order to support lower-memory configurations. If a
parameter is unspecified then the previously-defined value is used.

Conditionally set variables such as the softdevice RAM size, bootloader
size, and the spi m3 buffer size. This allows ports to adjust these
values to suit their needs.

The BLE Config area needs to be subtracted from the size of the firmware.
THis is because the firmware is counted by walking backwards from the end
of memory, and the BLE config area is placed lower in memory than the
firmware. Subtracting the BLE config size ensures the internal flash
filesystem doesn't try to use the firmware as storage.

This adds preliminary support for the nRF52833, which is a variant of
the nRF52840 with half the RAM, half the flash, and fewer peripherals.

Ports can set CIRCUITPY_RGBMATRIX and CIRCUITPY_FRAMEBUFFERIO to 0
in their .mk file in order to prevent these from being built. This
is necessary for resource-constrained devices.
