perf, x86: Fix uncore_types_exit section mismatch

Fix the following section mismatch:

WARNING: arch/x86/kernel/cpu/built-in.o(.text+0x7ad9): Section mismatch in reference from the function uncore_types_exit() to the function .init.text:uncore_type_exit()

The function uncore_types_exit() references the function __init
uncore_type_exit().  This is often because uncore_types_exit lacks a
__init annotation or the annotation of uncore_type_exit is wrong.

caused by 14371cc ("perf: Add generic PCI uncore PMU device
support").
