CVE-2023-53654

In the Linux kernel, the following vulnerability has been resolved:

octeontx2-af: Add validation before accessing cgx and lmac

with the addition of new MAC blocks like CN10K RPM and CN10KB
RPM_USX, LMACs are noncontiguous and CGX blocks are also
noncontiguous. But during RVU driver initialization, the driver
is assuming they are contiguous and trying to access
cgx or lmac with their id which is resulting in kernel panic.

This patch fixes the issue by adding proper checks.
