This adds support for the GRLIB SPIMCTRL SPI controller used in LEON and
NOEL-V systems. SPIMCTRL can operate in two different modes: In the
default mode it allows memory-mapped read access to the flash data. When
set in the user mode, it can be used to generate SPI bus transactions.

It looks like driver references quite a few non-existing properties in
devicetree (see dts/bindings/spi/infineon,cat1-spi.yml). This mistake
was hidden because of DT_INST_PROP_OR(), which expands to the default if
the property is not present. However, after
260fc89643, the issue became visible
because sme DT_INST_PROP_OR() were changed to DT_INST_PROP().
Note that only fields not initialized to 0 (or false) have been kept.

It might happens that DT(_INST)_PROP_OR is used with boolean properties.
For instance:
.single_wire = DT_INST_PROP_OR(index, single_wire, false), \
.tx_rx_swap = DT_INST_PROP_OR(index, tx_rx_swap, false), \
This is not required as boolean properties are generated with false
value when not present, so the _OR macro extension is superflous
and the above code can be replaced by:
.single_wire = DT_INST_PROP(index, single_wire), \
.tx_rx_swap = DT_INST_PROP(index, tx_rx_swap), \

This change marks each instance of the 'spi_driver_api' as 'static const'.
The rationale is that 'spi_driver_api' is used for declaring internal
module interfaces and is not intended to be modified at runtime.
By using 'static const', we ensure immutability, leading to usage of only
.rodata and a reduction in the .data area.

In the interrupt driven spi, spi_context_update_tx() is called once
from the calling thread and then once in spi_xmc4xxx_isr() after each
new byte is received. This actually means that there is one extra call to
spi_context_update_tx(). This is fine if spi_context_update_tx() complete
it's call in the calling thread before the interrupt fires, however, this
cannot be guaranteed especially if the calling thread is pre-emptive and
has a low priority.
Fix this by calling spi_context_update_tx() in the calling thread before
transmitting the first byte.
