spi: core and gpio expanders use subsys_init
Make the SPI external GPIO expander drivers register themselves at subsys_initcall() time when they're statically linked, and make the SPI core do its driver model initialization earlier so that's safe. SOC-integrated GPIOs are available starting very early -- often before initcalls start to run, or earily in arch_initcall() at latest -- so this improves consistency, letting more subsystems rely on GPIOs being usable by their own subsys_initcall() code.
