[PATCH] perf tools: Add missing Intel CPU events to parser

perf list expects CPU events to be parseable by name, e.g.

# perf list | grep el-capacity-read
el-capacity-read OR cpu/el-capacity-read/ [Kernel PMU event]

But the event parser does not recognize them that way, e.g.

# perf test -v "Parse event"
<SNIP>
running test 54 'cycles//u'
running test 55 'cycles:k'
running test 0 'cpu/config=10,config1,config2=3,period=1000/u'
running test 1 'cpu/config=1,name=krava/u,cpu/config=2/u'
running test 2 'cpu/config=1,call-graph=fp,time,period=100000/,cpu/config=2,call-graph=no,time=0,period=2000/'
running test 3 'cpu/name='COMPLEX_CYCLES_NAME:orig=cycles,desc=chip-clock-ticks',period=0x1,event=0x2/ukp'
-> cpu/event=0,umask=0x11/
-> cpu/event=0,umask=0x13/
-> cpu/event=0x54,umask=0x1/
failed to parse event 'el-capacity-read:u,cpu/event=el-capacity-read/u', err 1, str 'parser error'
event syntax error: 'el-capacity-read:u,cpu/event=el-capacity-read/u'
\___ parser error test child finished with 1
---- end ----
Parse event definition strings: FAILED!

Fix by adding missing Intel CPU events to the event parser.
Missing events were found by using:

grep -r EVENT_ATTR_STR arch/x86/events/intel/core.c
