Rajvi Jingar dd691e300d platform/x86/intel/pmc: Fix hang in pmc_core_send_ltr_ignore() 
[ Upstream commit fbcf67ce5a ]

For input value 0, PMC stays unassigned which causes crash while trying
to access PMC for register read/write. Include LTR index 0 in pmc_index
and ltr_index calculation.

Fixes: 2bcef45292 ("platform/x86:intel/pmc: Enable debugfs multiple PMC support")
