[bsp/raspberry-pi] update DM support

Browse Source 
- reorganize common Raspberry Pi drivers under the device framework
- add the Raspberry Pi 5 BSP, configuration and documentation
- add BCM2712 and DesignWare AXI DMA controller support
- distinguish BCM2712 DMA32 and DMA40 channels by channel mask
- restore DesignWare AXI DMA enable bits after controller reset
- support a shared AXI maximum burst length across DMA channels
