dmaengine: ste_dma40: Put the LCPA SRAM node

Browse Source 
of_parse_phandle() takes a reference to the LCPA SRAM node, but d40_probe()
does not release it after translating the node into a resource. This leaks
the node reference for the lifetime of the system.

Put the node immediately after of_address_to_resource() so both the success
and error paths release the reference.
