Merge ChibiOS and LUFA descriptor support (#2362)
* Move lufa descriptor to protocol/usb_descriptor * Try to compile usb_descriptor on ChibiOS * Add lufa_utils for ChibiOS Lufa USB descriptors for ChibiOS * More lufa_util compatibility fixes * First compiling version of shared USB descriptor * Send the usb descriptors * Fix the CONSOLE output on ChibiOS * Add errors for unsupported interfaces * Enable support for vitual serial port USB descriptors * Implement virtual serial port for ChibiOS * Cleanup the lufa_utils Use the default lufa header files * Add raw hid support for ChibiOS This is completely untested * Enable midi compilation on ChibiOS * Move midi functionality out of lufa.c * Don't register sysex callback when not needed * ChibiOS compilation fixes * Update ChibiOS submodule * Fix the Midi USB descriptor It didn't work properly when both Midi and Virtual serial port was enabled. * Add MIDI support for ChibiOS * Fix USB descriptor strings on ChibiOS * Use serial usb driver for raw hid * Generalize the ChibiOS stream like drivers This makes the initialization much more simple and eliminates a lot of the code duplication. * Convert console output to chibios stream driver * Fixes for ChibiOS update * Update the ChibiOS contrib submodule To include the usb data toggle synchronization fixes * Fix duplicate reset enumeration on ChibiOS * Add missing include * Add number of endpoints check for ChibiOS * Enable serial USB driver on all keyboards * Add missing includes when API is enabled withot midi * Add another missing inlcude
