Roger Clark	88d2457f30	STM32F1 core: Implemented changes already made to the GD32F1 core to use F_CPU instead of hard coded values for 72000000 and (F_CPU -1) instead of 71999999 and to replace other hard coded values related to the clock freqency. Also updated the code so that the USB clock was disabled in setup_clock_prescalers to allow it to be changed in that function during initialisation, in case altermative prescaler values for USB are required, e.g. for operation at 48Mhz	2015-09-06 07:51:40 +10:00
