spi: restructure kconfig options () Moves config options for each controllers into their own Kconfig files. This keeps upper level Kconfig from getting too big. () Options for each controller are moved under their own submenus.

license: Replace Apache boilerplate with SPDX tag Replace the existing Apache 2.0 boilerplate header with an SPDX tag throughout the zephyr code tree. This patch was generated via a script run over the master branch. Also updated doc/porting/application.rst that had a dependency on line numbers in a literal include. Manually updated subsys/logging/sys_log.c that had a malformed header in the original file. Also cleanup several cases that already had a SPDX tag and we either got a duplicate or missed updating.

kconfig: Hide the DesignWare SPI driver on unsupported platforms When users are configuring applications they are given the option to enable the DesignWare SPI driver. But they should not be given this option on SoCs that don't have the DesignWare SPI HW. This commit hides the driver by default by introducing the config option HAS_SPI_DW.

menuconfig SPI_DW
drivers/spi: Cleanup the Kconfig files Split QMSI relevant part into its own file. Some config where using prompt, some not: normalizing it by removing the prompt keyword where relevant. Reducing the file by using if/endif when relevant. However, it still not fully clean default: cfg and default baudrate should disappear. There is no default configuration to apply as long as the controller is not configured to run from any part using spi API. Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>
