don't define it as a "depend" variable in config/git/,
because it means putting the files in a subdirectory of
an existing project was was already then downloaded, and
that means it can't be downloaded first; if the download
of it fails, the old download is left intact.

this bug isn't currently fixed in the build system, at all,
so this and other patches are being made to mitigate it.

this brings the handling of serprog projects in sync
with canoeboot, which relies on the "depend" variable
to get the needed submodules, because cbmk does not
download submodules for these projects

lbmk does download submodules. i want it in sync with
cbmk for this, to make merging easier between both
projects, because i'm going to make a change on both
projects, whereby config/submodules/ is used exclusively

this merges the fix from:
https://codeberg.org/libreboot/pico-serprog/pulls/1

however, PRs are not to be sent there. riku merged it in
his repository, and i pulled it in the mirror hosted
on libreboot codeberg

Riku introduced three new patches:

* Add support for multiple chip selects. This allows you to
  control multiple chips from the same clip, on systems with
  dual flash setups, at least theoretically.
* Enable pull-up on unused chip selects - pull them high so
  that chips you connect that to are deactivated while flashing
  the target chip. This could be used on thinkpad W541 for
  instance, where miso/mosi have 0ohm between them via the two
  flash ICs. You could pull the other chip select high.
* Documentation for the above, in the pico-serprog readme.

This goes in tandem with a patch from Riku, present in the
recently integrated flashprog project, namely:

commit ddb6d926783d4f9cbee04c7392718ed8f89daa0e
Author: Riku Viitanen <riku.viitanen@protonmail.com>
Date:   Mon Jan 15 19:15:49 2024 +0200

    serprog: Add support for multiple SPI chip selects

This functionality will therefore be present in the next
release of Libreboot.

riku committed a new patch, that fixes build errors
when PICO_DEFAULT_LED_PIN is not defined, on a given
board. in such cases, riku's new patch just disables
handling of the status LED, but LEDs continue to work
on boards where it is defined.

the new revision sets drive level to 12mA instead
of the default 4mA. 16-20mA is the maximum tolerated
level for data lines, on most flash ICs, so 12mA is
relatively safe.

riku did this a while ago, tested on pico pi.

notabug is unreliable, even as a backup.

why, just today, it was offline! all day.

i originally moved libreboot away from notabug,
to codeberg instead, but kept the notabug account
online, and i still push to it when it's online.

however, notabug seems to be in a terminal state
of neglect by its admins, so lbmk should not use it.

it's now downloaded automatically as a submodule,
when downloading pico-sdk (which defines this module)
