Andrew Tridgell ea71b72c87 HAL_ChibiOS: fixed issue with I2C4 on H743 
when both I2C4 and SPI4 are active on a H743 I found that some BDMA
completion interrupts were lost, which resulted in SPI transfer
timeouts. Close inspection of the ChibiOS BDMA, I2Cv3 and SPIv3
drivers did not reveal any issues, but I found that the issue only
happened when the first 4 BDMA streams were used. This change splits
the 4 streams across the first and 2nd half of the BDMA controller,
and that fixes the problem.

This works as there are only 2 peripherals (I2C4 and SPI6) that want
to use BDMA with our current setup. If we ever wish to enable ADC3
(which also uses BDMA) we will need to revisit this issue

Andrew Tridgell a30e637484 HAL_ChibiOS: fixed bug in UART pin assignment 
this fixes an issue with the setting of pullup/pulldown on UARTs. It
also adds enforcement of DMA assignment for DMA required peripherals

Andrew Tridgell a59e1d0e0f HAL_ChibiOS: fixed H7 dma sharing between BDMA and DMA 
the BDMA and DMA controllers have separate namespaces for streams, so
we can allocate a lot more streams than we were
