After 5fa6863ba692 ("spi: Check we have a spi_device_id for each DT compatible") we need to add spi id_tables. Changing existing macro FBTFT_REGISTER_DRIVER would have meant to change arguments and therefore adjust all fbtft drivers.
This patch adds a new and simplified macro FBTFT_REGISTER_SPI_DRIVER that includes a spi id_table, and in addition to that: - does not define a platform driver - uses macro module_spi_driver()
