Fix dma-alloc and dma-map-in functions on board-js2x

Since slof/fs/dma-function.fs has been introduced for board-qemu,
these function definitions shadow the original js2x functions from
slof/fs/pci-config-bridge.fs, because dma-functions.fs is included
after pci-config-bridge.fs in slof/fs/pci-bridge.fs.
To restore the original behavior, move the js2x functions into
a board-specific dma-function.fs file instead and include that
one into the ROM-fs instead of the version for board-qemu.
