[PATCH] perf/x86/intel: constify array lbr_desc and make a function static

[Colin King]

From: Colin Ian King <colin.king@canonical.com>

A few minor clean-ups: constify array lbr_desc and make local
function lbr_from_signext_quirk_rd static to fix sparse warning:

"symbol 'lbr_from_signext_quirk_rd' was not declared. Should it be static?"
