The function blk_queue_max_hw_sectors() was removed in Linux v6.10 and
so add a test to conftest to see if this function is present or not to
allow the driver to build. The virtual-storage driver is currently
broken for Linux v5.19+ kernel due to other incompatibilities with these
newer kernels, but has been updated so that it still builds. Therefore,
allow the driver to build for Linux v6.10 while the driver is fixed
properly for these newer kernels.

Some of the conftest tests are no longer working with the mainline
kernel and this is causing various build failures for drivers. Upstream
commit a3b00f10da80 ("objpool: enable inlining objpool_push() and
objpool_pop() operations") inlined some code that causes build error to
occur when the tests are built with 'Werror=address-of-packed-member'.
Upstream commit 6f303d60534c ("gcc-9: silence 'address-of-packed-member'
warning") disables the option 'address-of-packed-member' for the kernel
already and so fix these new build failures by disabling this option
for the conftest tests.

Building the PCI EPF DMA test driver for Linux v6.9 is failing because
the parameters for the pci_epf_alloc_space() function has been updated
to pass the alignment value via the 'pci_epc_features' structure instead
of passing the value directly.
Instead of hard-coding the endpoint alignment in the EPF DMA test driver
use the 'pcie_epc_get_features()' function to retrieve the endpoint
features structure which has the endpoint alignment.
By using the conftest script to detect the parameters for the
pci_epf_alloc_space() function, we can then pass the appropriate
arguments to the pci_epf_alloc_space() function.

When adding conftest tests for detecting if specific functions are
present, it is always better to check if the newly added function is
present versus the function that has been removed. The reason being that
is the newly added function is modified in the future then the conftest
tests can be extended to check for updates to the function.
Therefore, instead of checking if the function gpiochip_find() is
present, which was removed in Linux v6.7, check if the function
gpio_device_find() is present, which replaced gpiochip_find in Linux
v6.7.
