spi: Provide new device instantiation macro

Again removing the prio parameter.

However, original macro does not seem to be used anywhere...

+/**
+ * @brief Like DEVICE_INSTANCE() with SPI specifics.
+ *
+ * @details Defines a device which implements the SPI API. May
+ * generate a custom device_state container struct and init_fn
+ * wrapper when needed depending on SPI @kconfig{CONFIG_SPI_STATS}.
+ *
+ * @param node_id The devicetree node identifier.
+ * @param init_fn Name of the init function of the driver.
+ * @param pm_device PM device resources reference (NULL if device does not use PM).
+ * @param data_ptr Pointer to the device's private data.
+ * @param cfg_ptr The address to the structure containing the configuration
+ *                information for this instance of the driver.
+ * @param level The initialization level. See SYS_INIT() for details.
+ * @param api_ptr Provides an initial pointer to the API function struct used by
+ *                the driver. Can be NULL.
