Fix xdma_if.m in an ACPI only kernel
- We depend on header polution to include sys/malloc.h. Include it
directly.
- Only define FDT-specific fuctions when building a FDT kernel.

Include opt_platform.h to ensure FDT is defined
We need to include opt_platform.h as it's where FDT will be defined.

o Add support for BERI IOMMU device
o Add an experimental IOMMU support to xDMA framework
The BERI IOMMU device is the part of CHERI device-model project [1]. It
translates memory addresses for various BERI peripherals modelled in
software. It accepts FreeBSD/mips64 page directories format and manages
BERI TLB.

Tune xDMA interface slightly:
o Move descriptors allocation to DMA engine driver
o Add generic xdma_request() routine
o Add less-generic scatter-gather application based on xdma interface
Typical operation flow in peripheral device driver is:
1. Get xDMA controller
sc->xdma_tx = xdma_ofw_get(sc->dev, "tx");
2. Allocate virtual channel
sc->xchan_tx = xdma_channel_alloc(sc->xdma_tx, caps);
3. Setup transfer status callback
xdma_setup_intr(sc->xchan_tx, my_tx_intr, sc, &sc->ih_tx);
4. Request a transfer(s)
ret = xdma_request(sc->xchan_tx, &req);
5. Free the channel
xdma_channel_free(sc->xdma_tx);
6. Free the controller
xdma_put(sc->xdma_tx);

Add xDMA -- the DMA abstraction layer, initial verison.
xDMA is a DMA framework designed to abstract the interaction
between device drivers and DMA engines.
