Also add the subnodes for the GPIO expander and NVMEM, and define the NVMEM layout. The NVMEM layout is declared such that it matches downstream's open-coded configuration [1]. The pinctrl nodes are kept sorted by the 'samsung,pins' property rather than node name, as I think that makes it easier to look at and to add new nodes unambiguously in the future.
