The Synopsys Designware SPI peripheral exists in two versions with
slightly different register layouts. Added a Kconfig option that makes the
driver compatible with the HSSI register layout.

For historical reasons, inversion mode is enabled by default in the
current implementation. This commit introduces an `inversion-off`
boolean DTS property, allowing it to be disabled if necessary.

The pinctrl driver actually uses SYSCON, so 'depends on' should be used
instead of 'select'. SYSCON should be selected in SoC config instead,
just like other SoC do.
This breaks Kconfig dependency loop for configs that indirectly depends
on SYSCON and causes PINCTRL to be selected.

When a target was registered with the controller but a controller-mode
request was performed, the driver failed to mask the interrupts that
were occurring as a result of the controller-mode transfer, causing an
interrupt flood. Ensure that all interrupts not handled by target mode
are handled as potential controller-mode events and acknowledged
properly.

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.

* 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.

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

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