[PATCH v4 1/3] perf/amd/ibs: Limit the max EILVT register count for AMD family 0x10

["Naveen N Rao (AMD)" <naveen@kernel.org>]

For AMD family 0x10, EILVT offsets are not assigned by BIOS and is
instead assigned by picking the next available EILVT offset.  Use the
maximum EILVT count for family 0x10 (APIC_EILVT_NR_AMD_10H) rather than
an arbitrary maximum EILVT count when looking for the next available
EILVT offset.
