Fix ChibiOS USB config for chips which support OTGv1 (#7564)

* Align endpoint config as per rest of file (fixes #4783)

* Add comments about explicit order use

* Update tmk_core/protocol/chibios/usb_main.c

/*
* Implementation notes:
*
* USBEndpointConfig - Configured using explicit order instead of struct member name.
* This is due to ChibiOS hal LLD differences, which is dependent on hardware,
* "USBv1" devices have `ep_buffers` and "OTGv1" have `in_multiplier`.
* Given `USBv1/hal_usb_lld.h` marks the field as "not currently used" this code file
* makes the assumption this is safe to avoid littering with preprocessor directives.
