It appears that a controller re-initialization is sometimes needed for
proper operation when handling target mode requests after a request from
the core is completed in controller mode. Add this re-initialization as
was already done between controller mode requests.

Apply changes which significantly speed up cache operations.
Removed k_busy_wait from function which polls for cache busyness.
Removed spinlock from cache operation. Lock taking and releasing
takes time and it is faster to check if LINEADDR changed
after performing the operation. If LINEADDR changed then it
indicates that current context was preempted by another cache
operation. If such state is detected current operation is
repeated.

Driver was disabling cache before full range operations and that
was causing hanging on polling for cache busy status since
state was never changing (because cache was disabled).
Additionally, added flushing to data cache disabling. If flushing
is not performed then execution fails since data in cache is lost.

When registering a target device, the driver will check if a slave address
is free in the peripheral. If so, the new slave address gets configured and

* Rename w5500_hw_reset to w5500_soft_reset.
This function performs a software reset, the GPIO reset is
hardware reset.
* Set thread name "eth_w5500".
* Simplify random MAC address code.
Remove unnecessary function pointer and wrapper function.
* Remove SPI read variable length array.
The VLA causes unnecessary stack usage and its max size changes
depending on CONFIG_NET_BUF_DATA_SIZE.
Split the SPI read into two transactions, a skip of the first 3
dummy bytes, then a read of the data directly into to given buffer.
* Remove unused variables config_func and full_duplex.

For many of the state checks with timeout, the check

Align the SPI init priority with other devices.
Other bus-devices like UART and I2C are init at standard kernel

a reason for it.
GPIO is init at 40 so there should not be an issue to use the default.

This adds automatic GPIO latching before going to extended sleep and
restoring state after wakeup.
Mode and state for each pin is stored, then ports are latched to retain
state when PD_COM is disabled during sleep. On wakeup mode and state for

- Update the DAI SSP configuration functions to use the new management
approach.
- Update device tree bindings and instances to reflect the new SSP IP
