arm64: Use insert_resource() to simplify code
insert_resource() traverses the subtree layer by layer from the root node
until a proper location is found. Compared with request_resource(), the
parent node does not need to be determined in advance.
In addition, move the insertion of node 'crashk_res' into function
reserve_crashkernel() to make the associated code close together.
