The Atmel SAM0 SoC enable peripherals clocks in distinct places: PM and
MCLK. The old devices had defined the peripheral clock enable bit at PM.
On the newer devices this was extracted on a dedicated memory section
called Master Clock (MCLK). This change excludes the dedicated bindings
in favor of a generic approach that cover all cases.
Now the clocks properties is complemented by the atmel,assigned-clocks
property. It gives the liberty to user to customize the clock source
from a generic clock or configure the direct connections.
All peripherals drivers were reworked with the newer solution.

Add support for the I2C_MSG_RESTART flag to be able to use a
repeated start in between chained transactions.
The driver now uses the stop/restart flags set in the i2c_msg,
instead of starting and stopping for each transaction in the chain.

RTIO correctly declares tx buffers as const, however, the
existing I2C API and NRFX (SDK) drivers don't. Therefor cast the
const buf to non-const when passing the tx buf to the twim driver
from the RTIO call to avoid the const warning.
The tx buffer is being treated as const data naturally in the
NRFX driver, its just not declared as such since we reuse the
buffer for both RX and TX data.
Alternatively the SDK and "shim" drivers built on top of it need
to be updated, which is quite a bit of work :)

If CONFIG_I2C_STATS is enabled, the device state for all I2C controller
drivers must contain the I2C stats. This space is allocated by calling
Z_I2C_INIT_FN as part of the device definition; this is done automatically
when using I2C_DEVICE_DT_DEFINE instead of DEVICE_DT_DEFINE. If space
for statistics is not properly allocated but CONFIG_I2C_STATS is enabled,
an unexpected write to memory outside of the stats region may occur on
an I2C transfer. This commit uses I2C_DEVICE_DT_DEFINE or
I2C_DEVICE_DT_INST_DEFINE for all in-tree SPI controller drivers that do
not already.

Transactions from RTIO should result in single calls to i2c_transfer.
This corrects the default handler to first count the number of
submissions in the transaction, allocate on the stack, and then copy
over each submission to an equivalent i2c_msg.
It also cleans up the helper functions to be infallible, taking only the
submission and msg to copy to.
