Bringing Massdrop keyboard hardware configuration to keyboard level (#4593)
MCU Pins for debugging, LED, boot tracing, and shift registers are now configurable at keyboard level. Macros led_* replaced by DBG_LED_* Macros m15_* replaced by DBG_1_* Macros m27_* replaced by DBG_2_* Macros m28_* replaced by DBG_3_* For CTRL and ALT keyboards, debug boot tracing pin default now set to pad M27 instead of M28 since although M28 is not being used, it is technically a signal for USB port detection. m15_print(...) renamed to dbg_print(...) to get away from hard coded port names. dbg_print function now follows similar pattern to debug led output.
