The current bcm63xx_enet driver always uses bcmenet_shared_base whenever
it needs to access DMA channel configuration space or access the DMA
channel state RAM. Split these register in 3 parts to be more accurate:

- global DMA configuration
- per DMA channel configuration space
- per DMA channel state RAM space

This is preliminary to support new chips where the global DMA
configuration remains the same, but there is a varying number of DMA
channels located at a different memory offset.

These were erroneously copied from BCM6368. BCM6328 does not expose the
ENETSW_TXDMA interrupts, and BCM_6328_HIGH_IRQ_BASE + 7 is actually used
for the second UART.

lacking the appropriate drivers, no support for attached flash.

This register was introduced with the support of the BCM6368 CPU in the idea
that its internal layout was different from the other CPUs SPI controller.
The controller is actually the same as the one present on BCM6358 so we can
remove this register and use the usual SPI register instead.

Though BCM6345 does not technically have the same MPI register layout
than the other SoCs, reading the chip-select registers is done the same
way, and particularly for chip-select 0, which is the boot flash.

The BCm63xx SOC has two uarts.  Some boards use the second one for
bluetooth.  This patch changes platform device registration code to
handle this.  Changes to the UART driver were already merged in
