Bug#1121155: xrt-xocl-dkms: module fails to build for Linux 6.18: error: implicit declaration of function 'ida_simple_get'

[Andreas Beckmann]

Followup-For: Bug #1121155

Linux v6.18 support seems to be fixed in the last upload, but one change
for supporting older kernels was missed upstream (in addition to the two
changes for setting BUILD_EXCLUSIVE_KERNEL_MIN and a missing #include I
previously mentioned here), patch attached.
