Support gathering multiple message buffers into a single write
transaction, and scattering read data from a single transaction
to multiple message buffers.
This is required for the i2c_burst_write() API to function as
expected.
The implementation uses a driver-internal buffer whose size is
configurable through the `zephyr,concat-buf-size` devicetree
property for similarity with other I2C drivers in the tree.
Gather write is implemented for both interrupt and DMA based
transfers, while scatter read is only implemented for interrupt
based transfers at this time. In the future, DMA based gather
write should be delegated to the DMA engine to perform
autonomously without needing a temporary buffer.

Since the system node has not been used for a long time,
it should be removed to allow other peripheral nodes to define
the register without being child nodes of the system node.

According to NXP AN12949 (2.1.2) and UM11295 (2.1.5/10.1), the size of
the Protected Flash Region (PFR) is 12 KB, located at 0x3d000 to 0x3ffff,
and included in all LPC55S1x/LPC551x devices.
The common DTS include file for all LPC55S1x/LPC551x devices is intended
to provide the maximum flash memory configuration for 256 KB devices and
can therefore only allocate 244 KB for customer-usable flash memory. The
PFR must be 12 KB in size and bound to address 0x3d000.

Modifies 1-wire serial driver to accept configurable baud rates for
Overdrive mode.
In testing with DS2488, which are Overdrive-only, it was found that
both the baud rate and zero bit pattern needed to be adjusted for
stability. This commit allows the user to define their own baud
rates for OD mode, and modifies the zero bit in OD mode.
It is assumed that most testing has been done with standard-speed
devices, so the timings and bit patterns have not been changed or
made user-modifiable.
