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.

spi: For spi_dw, added SPI_DW_FIFO_DEPTH as configurable paramter When using the Synopsys DesignWare Synchronous Serial Interface (SSI), the FIFO depth can vary from 2-256, depending upon how this module is built. For quark_se_ss, it was using a depth of 8. For EM Starterkit, it will be 32. Adding this now as a configurable option. A larger FIFO really helps reduce SPI interrupts.
