The build of driver is disabled from Linux 6.2 due to
changes in core kernel where API of_get_named_gpio_flags()
has been removed.
This APIS is removed in commit 40fc56ee608cdb ("gpiolib:
of: remove of_get_gpio[_flags]() and of_get_named_gpio_flags()")
in Linux 6.2.
Add support to use the new APIs for Linux 6.2 onwards.

For Linux v6.8, support for SPI controllers with multiple chip-selects
was added to the SPI core and this updated the 'chip_select' member of
the 'spi_device' structure to be an array. This breaks building the
Tegra124 SPI Slave driver and Tegra210 QUAD SPI driver.
A helper function, spi_get_chipselect(), was added for Linux v6.3 to
retrieve the chip-select for a SPI device and can be used for retrieving
the chip-select for all Linux v6.3+ kernels.
Add a conftest rule to detecting if spi_get_chipselect() is present and
if so use this for getting the chip-select. This fixes the build issues
for Linux v6.8.

Rather than using kernel version checks to determine which kernel APIs
to use, add the necessary tests to the conftest script to determine
which kernel APIs are present in the kernel.
Note that the function snd_soc_dai_init_dma_data() has been present
in the Linux kernel since v3.13 and so use this for all kernel versions.
In Linux v6.3, the 'playback_dma_data' and 'capture_dma_data' members of
the snd_soc_dai_driver structure were replaced and so these could no
longer be set directly. However, the arguments to
snd_soc_dai_init_dma_data() have not changed and so can be used for
older kernels and well has the current.
This is beneficial for working with 3rd party Linux kernels that may
have back-ported upstream changes into their kernel and so the kernel
version checks do not work.
