Update GPIO pullup/pulldown code to support Pi4
Detail: * Fixes register corruption in GPIOPullDirection. * Pre-seeds the soft copies with the values from the datasheet (so no need for a function to read them). This should also help other models of Pi which assumed they were all disabled when it seems they are not! * Reworks the SDIO driver to call through to the GPIO so that its softcopy is kept in sync, and so the settings do something on a Pi 4 at all. Admin: Tested on Pi4 and a Pi 3B+. Version 0.91. Tagged as 'HAL_BCM2835-0_91'
