Change in simtrace2[master]: firmware: add definition for main osc bypass when using external osc

laforge has submitted this change. ( https://gerrit.osmocom.org/c/simtrace2/+/26861 ) Change subject: firmware: add definition for main osc bypass when using external osc ...................................................................... firmware: add definition for main osc bypass when using external osc Add new board.h definition BOARD_MAINOSC_BYPASS to configure the clock module to use an external oscillator rather than a crystal. The qmod board is one such board.
