* Update ChibiOS-Contrib for USB suspend fixes
* Remove S3 wakup workaround
ChibiOS OTGv1 driver has a remote wakeup bug that prevents the device to
resume it's operation. 02516cbc24
introduced a hotfix that forcefully restarted the usb driver as a workaround.
This workaround broke multiple boards which do not use this driver /
peripheral. With the update of ChibiOS this hotfix is now obsolete.
* Remove restart_usb_driver overrides
they are no longer necessary as the workaround is not needed anymore
for stm32f4
* Remove unused RP_USB_USE_SOF_INTR defines
The SOF interrupt is enabled dynamically by the RP2040 usb driver
According to the USB 2.0 spec, remote wakeup should be disabled by
default, and should only be enabled if the host explicitly requests
it. The chibios driver code already takes care of storing this
information, and returning it on GET_STATUS requests. However our
application code has been ignoring it so far.
This is a USB compliance issue, but also a bug that causes trouble
in some cases: On RP2040 targets this has been causing problems if
a key is held down while the keyboard is plugged in. The keyboard
would fail to enumerate until all keys are released. With this
change that behavior is fixed.
Note that for LUFA targets this is already done correctly.
In #18631 some IN notification callbacks that were doing nothing were
removed, which should be a valid thing to do (ChibiOS HAL checks the
`in_cb` and `out_cb` pointers for being non-NULL before invoking those
optional callbacks). However, it turned out that some less popular USB
LLDs (KINETIS and MIMXRT1062) have their own checks for those pointers,
and (incorrectly) skip the ChibiOS callback handling when those pointers
are NULL, which breaks the code for the `USB_USE_WAIT` configuration
option (the waiting thread never gets resumed if the corresponding
callback pointer is NULL).
Add those dummy callbacks again (but use a single function for all of
them instead of individual ones for each endpoint); this restores the
KINETIS and MIMXRT1062 boards to the working state while the LLDs are
getting fixed.
* Fix unaligned memory access in config blob handler
data* points in the middle of an u8 array, casting this to an u16* and
dereferencing it leads to an unaligned memory access - which hardfaults
on Cortex M0 mcus e.g. RP2040s.
* Actually read until there is no more data to be read
* Disable RESET keycode because of naming conflicts
* Add Pico SDK as submodule
* Add RP2040 build support to QMK
* Adjust USB endpoint structs for RP2040
* Add RP2040 bootloader and double-tap reset routine
* Add generic and pro micro RP2040 boards
* Add RP2040 onekey keyboard
* Add WS2812 PIO DMA enabled driver and documentation
Supports regular and open-drain output configuration. RP2040 GPIOs are
sadly not 5V tolerant, so this is a bit use-less or needs extra hardware
or you take the risk to fry your hardware.
* Adjust SIO Driver for RP2040
* Adjust I2C Driver for RP2040
* Adjust SPI Driver for RP2040
* Add PIO serial driver and documentation
* Add general RP2040 documentation
* Apply suggestions from code review

...when attempting to start a receiving USB transfer. Previously, we would
check on the IN endpoint which is the transmitting part of the USB endpoint.
This is wrong and lead to two USB transfers being started immediately
after each other in case of e.g. RAW HID endpoints:
1. When finishing an OUT transfer the low level USB driver calls the out_cb
callback, which in turn initiates another OUT transfer by calling
qmkusbDataReceived.
2. When the raw hid receive channel runs empty inside the raw_hid task,
another OUT transfer is started to potentially fill the channel again. This
happens by calling ibnotify.
Both events occur directly after each other, thus triggering the bug.
