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.
* the size variable was redeclared (hiding the variable of the outside scope) and therefore the while check was always false, so the compiler just removed the do while loop, but it would be better to read all data and only exit the task, after this is done
