Jeff Epler 4adbd23b75 stm: Add sdioio support for feather_stm32f405_express
Currently, only the bus specs of the stm32f405xx have been coded.
Other stm-family chips need (at a minimum) the specs added in their
periph.[ch] files.

Jeff Epler 57ab4f1329 stm: SPI: revamp pin search code
I discussed with Hierophect on Discord about how to "de-nest" the code
for configuring SPI objects on STM, because the problems with one
nesting level per pin becomes unmanageable with the up to 10 pins of
SDIO.

This code (which is only compile-tested so far) demonstrates the concept
we discussed.

The SCK pin is always required.  Loop over all possibilities of the SCK
pin.  When we are considering a particular item in the mcu_spi_sck_list
we have now become committed to using a particular periph_index.  If all
the other pins can be satisfied by that periph_index, then we have a
working combination.  Once we have a working combination that is not
reserved, we can return that combination.  On reaching the end, we have
checked all the possible possibilities and can give the same errors as
before: One if there was a possibility that worked but was reserved;
and another if no possibility worked.

Merge remote-tracking branch 'adafruit/master' into lower_power
This isn't perfect and needs a bit more testing.

Lucian Copeland c4db8b87e2 Add F7 and H7 Support to the STM32 port
Restructures the STM port of Circuitpython to be more generic about the STM32 chip lines to support
the F7 and H7 series of chips. Adds the new Packages directory to organize different chip layouts
between lines. Makes general changes to the Makefile to condense board-level flags to the minimum
and support the new chip series. Adds the new chip line to the Peripherals directory, along with
new python tools used to generate peripheral text automatically in the tools/ directory.
