Move pinmux alloc/dealloc code into functions that don't take
the spinlock so we can use from code that has the spinlock already.
CRISv32 has no working SMP, so spinlocks becomes a NOP,
so deadlock was never seen.

`port' is used as index for writing to pins during
allocation/deallocation. It should be positive.

The two chips are somewhat different, and needs different handling.
Adds handing of the dma, dram initialization, hardware settings, io,
memory arbiter and pinmux
Also moves the dma, dram initialization and io from CRIS v32 common files.
