This patch introduces sys_mm_drv_move_region implementation
which stops usage of the sys_mm_drv_simple_move_region.
The sys_mm_drv_simple_move_region is unsuitable becuase
it iterates through physical pages in linear fashion.
The new implementation queries the tlb for each virtual
page of the requested region to find the physical page
to be remapped.

The SSD16xx driver needs to wait for the chip to complete commands
before issuing new commands. The datasheet doesn't specify which
commands cause the chip to raise the busy pin. The current driver has
ssd16xx_busy_wait() calls after commands that are known to take a long
time. This is very fragile and scatters a lot of boiler plate around
the driver.
Include an ssd16xx_busy_wait() call in ssd16xx_write_cmd() instead of
after commands that are suspected to take a long time. This makes the
driver more robust and is more in line with the expectations set out
in the data sheet.

There are cases when attributes of mapped virtual memory need
to be updated. E.g. in case there is loadable library/module
code loaded to the l2 memory then memory needs to be read-write.
After the code is loaded and is ready to be executed then
attributes of mapped memory should be updated to
read-only/executable without loosing memory contents.

Refactors counter driver code, bringing:
- more readability through the removal of abused macros
- better use of the devicetree, by moving peripheral node's
info defined on macros and Kconfigs to dts bindings
- less dependence from dynamic allocations, making counter
instances fully statically-allocated
- better use of DT_INST_* macros

Move the CAN bus network driver from drivers/can to drivers/net as it
implements a network driver, not a CAN controller driver.
Use a separate Kconfig for enabling the CAN bus network driver instead of
piggybacking on the SocketCAN Kconfig. This allows for other
(e.g. out-of-tree) SocketCAN transports.

Implement support for display blanking by inhibiting display refresh
while blanking is on. Writes to the display are still sent to the
internal RAM in the display controller. Once blanking is turned off,
the contents of the RAM are written to the display. This behavior is
makes it possible to compose a frame buffer in the display controller
without flickering.
Other e-paper drivers such as the GD7965 already implement this
behavior.

Adding command queue mode can reduce the time between each byte to
improve the I2C bus clock stretching during I2C transaction.
I2C command queue mode of it8xxx2 can support I2C APIs including:
i2c_write(), i2c_read(), i2c_burst_read.
Test:
1. tests\drivers\i2c\i2c_api --> pass
2. Reading 16 bytes of data through i2c_burst_read() can reduce
0.72ms(2.54ms->1.82ms) compared to the original pio mode when the
frequency is 100KHz.
3. krabby platform can boot normally.

Simplify the implementation by using gpio_dt_spec.
As part of this use logical values of 0/1 for gpio_pin_set_dt

Implement support for half duplex communication in the bit bang SPI
driver. The SPI driver will use the MOSI pin is for both TX and RX
operations when using half duplex mode.
In half-duplex mode, the driver configures the MOSI pin as an input
pin for input only transactions. Transactions that are bidirectional
are forbidden. After an SPI transaction, the MOSI pin is left as an
input if it was an RX transaction or an output after a TX
transaction. Like before, the MOSI pin is initialized as an
(inactive) output pin when the bus is initialized.

Remove the support for enabling passthrough mode support for MPU9150
on the AK8975. We don't have a proper MPU9150 driver and the MPU9150
has been EOL. So its highly unlikely this code is being used.
Additonally we remove the device tree binding for the MPU9150 since
we don't have a proper driver for it.

CONFIG_SIFIVE_SPI_0_ROM (default y) was an option to disable spi0 if
used to access SPI Flash ROM. However, its design had a problem: it
relied on instance numbers. You had to set status okay for spi0 to make
it work (incongruent with the purpose of the option itself). This patch
makes things simpler: if such SPI0 is not available, simply keep it
disabled in DT. Bindings have been updated to mention this case.
