Mark the I2C instances as `PM_DEVICE_ISR_SAFE`, as the transition
operations are short, it saves RAM resources, and the spin-locking fixes
the non-atomic behaviour of the PM usage counter.

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.

left as a TODO. Similarly, I lack the hardware to test

- Driver always initializes the device in the suspended state
- If CONFIG_PM_DEVICE_RUNTIME=n, device PM callback will be called with
RESUME action, thus setting up pins to default state and enabling the
peripheral
NOTE: when CONFIG_PM_DEVICE=n, the pinctrl sleep state will not be
available (-ENOENT) and so never applied, thus avoiding a pin
suspended->active transition.
