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: Use a short, consistent style for prompts Consistently use config FOO bool/int/hex/string "Prompt text" instead of config FOO bool/int/hex/string prompt "Prompt text" (...and a bunch of other variations that e.g. swapped the order of the type and the 'prompt', or put other properties between them). The shorthand is fully equivalent to using 'prompt'. It saves lines and avoids tricking people into thinking there is some semantic difference. Most of the grunt work was done by a modified version of https://unix.stackexchange.com/questions/26284/ how-can-i-use-sed-to-replace-a-multi-line-string/26290#26290, but some of the rarer variations had to be converted manually.

bool "Shared interrupt driver"
drivers: add shared interrupt driver This driver allows multiple drivers to share a common interrupt line. This functionality is required on system that conform to the PC interrupt structure. In the context of Zephyr this is needed for SOC's that have their I/O IP blocks behind a PCI interface. Due to the limited number of interrupt lines provided by the PCI interface multiple IP blocks may be configured to share an interrupt line. Drivers that share interrupts must be modified to *not* register their own interrupt service routine as part of their configuration/initialization but instead bind to the correct instance of this driver by name, then register their interrupt service routine with this driver.

refactor common driver initialization priorities Most of the SoC and board Kconfig use the same values for driver initialization priorities. So refactor them, and discard duplicate ones. The shared IRQ init priority was changed so that the kernel default init and device init priorities can be standardized across all SoC/boards. Same goes for DesignWare SPI driver. This also changes the UART_CONSOLE_PRIORITY and IPM_CONSOLE_PRIORITY to UART_CONSOLE_INIT_PRIORITY and IPM_CONSOLE_INIT_PRIORITY, to standardize across all drivers. Note that this does not take away the ability to override those values. This just provides reasonable defaults such that there is virtually no need to override.

Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1, SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug where the documentation specified SECONDARY ran before the kernel started up, but actually ran afterwards.
