perf vendor events intel: Fix wrong filter_band* values for uncore events

BugLink: https://bugs.launchpad.net/bugs/1836802
[ Upstream commit 94aafb74cee0002e2f2eb6dc5376f54d5951ab4d ]

Michael reported that he could not stat following event:

  $ perf stat -e unc_p_freq_ge_1200mhz_cycles -a -- ls
  event syntax error: '..e_1200mhz_cycles'
                                    \___ value too big for format, maximum is 255
  Run 'perf list' for a list of valid events

The event is unwrapped into:

  uncore_pcu/event=0xb,filter_band0=1200/

where filter_band0 format says it's one byte only:

  # cat uncore_pcu/format/filter_band0
  config1:0-7

while JSON files specifies bigger number:

  "Filter": "filter_band0=1200",

all the filter_band* formats show 1 byte width:

  # cat uncore_pcu/format/filter_band1
  config1:8-15
  # cat uncore_pcu/format/filter_band2
  config1:16-23
  # cat uncore_pcu/format/filter_band3
  config1:24-31

The reason of the issue is that filter_band* values are supposed to be
in 100Mhz units.. it's stated in the JSON help for the events, like:

  filter_band3=XXX, with XXX in 100Mhz units

This patch divides the filter_band* values by 100, plus there's couple
of changes that actually change the number completely, like:

  -        "Filter": "edge=1,filter_band2=4000",
  +        "Filter": "edge=1,filter_band2=30",
