perf/x86/intel/uncore: Fix oops when counting IMC uncore events on some TGL

When counting IMC uncore events on some TGL machines, an oops will be
triggered.
  [ 393.101262] BUG: unable to handle page fault for address:
  ffffb45200e15858
  [ 393.101269] #PF: supervisor read access in kernel mode
  [ 393.101271] #PF: error_code(0x0000) - not-present page

Current perf uncore driver still use the IMC MAP SIZE inherited from
SNB, which is 0x6000.
However, the offset of IMC uncore counters is larger than 0x6000,
e.g. 0xd8a0.

Enlarge the IMC MAP SIZE for TGL to 0xe000.
