x86/platform/UV: Mark tsc_check_sync as an init function

Fix build problem:

>> WARNING: vmlinux.o(.text+0x4223a): Section mismatch in
   reference from the function uv_tsc_check_sync() to the function
   .init.text:uv_early_read_mmr() The function uv_tsc_check_sync()
   references the function __init uv_early_read_mmr().  This is often
   because uv_tsc_check_sync lacks a __init
