CRISv32: ETRAXFS: Fix recursive spinlock
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. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>
