The txt binding specified the property "power-supply".
But the example and the actual implementation in the linux-kernel
uses "avdd-supply".
So the binding is adjusted to use avdd-supply as this seems
to be the correct choice.
There are no DT files in the linux kernel to check.

siw_fastreg_mr() invokes siw_mem_id2obj(), which returns a local reference
of the siw_mem object to "mem" with increased refcnt. When
siw_fastreg_mr() returns, "mem" becomes invalid, so the refcount should be
decreased to keep refcount balanced.
The issue happens in one error path of siw_fastreg_mr(). When "base_mr"
equals to NULL but "mem" is not NULL, the function forgets to decrease the
refcnt increased by siw_mem_id2obj() and causes a refcnt leak.
Reorganize the flow so that the goto unwind can be used as expected.
