There is a dependency loop between fuses, clocks, and APBDMA.
If dma is enabled, fuse reads must go through APBDMA to avoid
corruption due to a hw bug.  APBDMA requires a clock to be
enabled.  Clocks must read a fuse to determine allowable cpu
frequencies.

Separate out the fuse DMA initialization, and allow the fuse
read and write functions to be called without using DMA before
the DMA initialization has been completed.  Access to the fuses
before APBDMA is initialized won't hit the hardware bug because
nothing else can be using DMA.
