spi: Use different hooks for SPI enable/disable
If CONFIG_CHIPSET_RESUME_INIT_HOOK is defined, move the SPI
enable/disable to different hooks, i.e.
* RESUME_INIT instead of RESUME
* SUSPEND_COMPLETE instead SUSPEND
The SPI interface has to be enable earlier than other hooks
to receive a host sleep event.
