Implement a new stable-poll-period-ms property to specify a new (slower)
polling rate for when the matrix is stable.
The keyboard thread can eat up a surprisingly high amount of cpu cycles in
busy waiting if the specific hardware implementation happen to have a
particularly slow settle time, but high frequency polling is really only
needed when debouncing.
The new property allow slowing down the polling rate when the matrix is
stable (either key pressed but none to be debounced or idle in the case
of the gpio implementation with no interrupts), this allows reducing the
overall cpu time taken by the keyboard scanning thread when keys are
persistently pressed.

The newest AN1760 application note - Revision F (DS60001760G - June 2024)
is recommending to not write the node count to PLCA_CTRL1 register when
the node is not the PLCA coordinator (i.e. its ID is not zero).

This patch brings update of the procedure to initially configure the
LAN865x devices. It follows setup guidelines from newest AN1760 [*].
The values from "TABLE1" on the [*] must be written to the device in the
indicated order with recommended values.
This was not the case previously, as first values from in-flash allocated
(const) table were written and only afterwards calculated configuration
parameters (cfgparams) were updated.
With this patch the lan865x_conf[] table is allocated in-RAM, so
placeholder values can be updated and it can be written at once at the
end of configuration process.
Its single entry has been reduced from 8B to only 4B. Moreover, moving
it out of flash saves 512B of flash memory.

The it8xxx2_kbd KSO pins can be used as both keyboard scan and GPIO. By
default the keyboard scanning driver controls the output level of all
the KSO signals from 0 to (col-size - 1), meaning that any line in
between used as GPIO is going to have its output value overridden.
Add a kso-ignore-mask property to the keyboard scan driver to allow
specifiying extra pins that should not be controlled by the driver.

The tx fifo empty interrupt is a edge driven interrupt, so if it
is already empty then and the interrupt is enabled, it will not
fire so the isr needs to be triggered manually for the callback.
This also removes the unnecessary interrupt locking in the isr and
removes the receiver timeout interrupt.

Obviously, everyone knows that there are 8 bits per byte, so
there isn't a lot of magic happening, per se, but it's also
helpful to clearly denote where the magic number 8 is referring
to the number of bits in a byte.
Occasionally, 8 will refer to a field size or offset in a
structure, MMR, or word. Occasionally, the number 8 will refer
to the number of bytes in a 64-bit value (which should probably
be replaced with `sizeof(uint64_t)`).
For converting bits to bytes, or vice-versa, let's use
`BITS_PER_BYTE` for clarity (or other appropriate `BITS_PER_*`
macros).

Use minimized PIO code for 3-wire operation.
Input and output buffers are conventionally stored in bus byte order.
For 16 and 32 bit transfers, this is effectively big-endian, so
txbuf and rxbuf need to be read as such. Those pointers also need
to be declared uint8_t * instead of void *.
In addition, tx_count and rx_count are based on dts, and refer to
whole transfers (8, 16, or 32 bits), not bytes.
Added rpi_pico.overlay to samples/sensor/magn_polling to demonstrate
32-bit word size, and updated the README.rst to make it independent
of the specific sensor.
