Subject: [PATCH] perf vendor events intel: Add uncore_upi JSON support

From: Kan Liang <kan.liang@...ux.intel.com>

Perf cannot parse UPI events.

    #perf stat -e UPI_DATA_BANDWIDTH_TX
    event syntax error: 'UPI_DATA_BANDWIDTH_TX'
                     \___ parser error
    Run 'perf list' for a list of valid events

The JSON lists call the box UPI LL, while perf calls it upi.
Add conversion support to json to convert the unit properly.
