d68666fc08 drivers: spi: sam0: Implement DMA async API
This adds support for the async API for SAM0 SERCOM SPI using
DMA to drive the device.  This implementation does the reload
for both transmit and receive in the receive DMA handler.
Doing this simplifies the implementation but means that the
transmit drains completely, resulting in the SPI clock pausing
between buffers while both are reloaded in the receive handler.

Tested with tests/drivers/spi/spi_loopback and several simple
programs monitored with a logic analyzer.

e1639b5345 device: Extend device_set_power_state API to support async requests
The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.

To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.

This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.

4344e27c26 all: Update reserved function names
Update reserved function names starting with one underscore, replacing
them as follows:
   '_k_' with 'z_'
   '_K_' with 'Z_'
   '_handler_' with 'z_handl_'
   '_Cstart' with 'z_cstart'
   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

Various generator scripts have also been updated as well as perf,
linker and usb files. These are
   drivers/serial/uart_handlers.c
   include/linker/kobject-text.ld
   kernel/include/syscall_handler.h
   scripts/gen_kobject_list.py

8206ed42ec kconfig: drivers: spi: Remove duplicated dependencies
The two redundant SPI dependencies are from 'source'ing a file within an
'if SPI' and then adding another 'depends on SPI' within it.

'if FOO' is just shorthand for adding depends on FOO to each item within
the 'if'. There are no "conditional includes" in Kconfig, so 'if FOO'
has no special meaning around a source. Conditional includes wouldn't be
possible, because an if condition could include (directly or indirectly)
forward references to symbols not defined yet.

Tip: When adding a symbol, check its dependencies in the menuconfig
('ninja menuconfig', then / to jump to the symbol). The menuconfig also
shows how the file with the symbol got included, so if you see
duplicated dependencies, it's easy to hunt down where they come from.

75f77db432 include: misc: util.h: Rename min/max to MIN/MAX
There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when
using some STL headers i.e. <chrono>.

This is because there are actual C++ functions called min and max
defined in some of the STL headers and these macros interfere with them.
By changing the macros to UPPERCASE, which is consistent with almost all
other pre-processor macros this naming conflict is avoided.

All files that use these macros have been updated.
