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.

Initial support for Microchip MEC1501 series is added to the tree.
Additional support for UART is also included. This SoC supports

Add a Kconfig option to enable DMA for SPI with SOC_NRF52832 as long as
it being disabled due to Product Anomaly Notice (PAN) 58 is explicitly
overridden. This allows the SPIM driver to be enabled for the nRF52832
SoC for situations where PAN 58 is not a problem.

Same deal as in commit 4638652214 ("Kconfig: Use 'default' instead of
'def_bool' in Kconfig.defconfig files"), fixing new stuff that got
introduced since then.
Some symbols, like ALTERA_AVALON_PIO, are only defined in
Kconfig.defconfig files, and so need the def_bool.
Motivation (from the note at the end of
guides/kconfig/index.html#common-shorthands):
For a symbol defined in multiple locations (e.g., in a Kconfig.defconfig
file in Zephyr), it is best to only give the symbol type for the "base"
definition of the symbol, and to use 'default' (instead of 'def_<type>'
value) for the remaining definitions. That way, if the base definition
of the symbol is removed, the symbol ends up without a type, which
generates a warning that points to the other definitions. That makes the
extra definitions easier to discover and remove.

There exists SoCs, e.g. STM32L4, where one of the low power modes
reduces CPU frequency and supply voltage but does not stop the CPU. Such
power modes are currently not supported by Zephyr.
To facilitate adding support for such class of power modes in the future
and to ensure the naming convention makes it clear that the currently
supported power modes stop the CPU this commit renames Low Power States
to Slep States and updates the documentation.

The iMX RT1060 and RT1064 have additional dedicated 512KB on-chip ram.

which is moved to 0x20280000 in order to guarentee global OCRAM memory
continuity regardless OCRAM1 size configuration (256KB by default).
In default configuration, this gives 768KB (512+256) on-chip ram:
0x20200000 to 0x202BFFFF.
