perf/x86/intel/uncore: Add Broadwell-U uncore IMC PMU support
This patch enables the uncore Memory Controller (IMC) PMU
support for Intel Broadwell-U (Model 61) mobile processors.
The IMC PMU enables measuring memory bandwidth.
To use with perf:
$ perf stat -a -I 1000 -e
uncore_imc/data_reads/,uncore_imc/data_writes/ sleep 10
