Likhitha Korrapati 7e442be701 perf tools: Fix is_compat_mode build break in ppc64 
Commit 54f9aa1092 ("tools/perf/powerpc/util: Add support to
handle compatible mode PVR for perf json events") introduced
to select proper JSON events in case of compat mode using
auxiliary vector. But this caused a compilation error in ppc64
Big Endian.

arch/powerpc/util/header.c: In function 'is_compat_mode':
arch/powerpc/util/header.c:20:21: error: cast to pointer from
integer of different size [-Werror=int-to-pointer-cast]
   20 |         if (!strcmp((char *)platform, (char *)base_platform))
      |                     ^
arch/powerpc/util/header.c:20:39: error: cast to pointer from
integer of different size [-Werror=int-to-pointer-cast]
   20 |         if (!strcmp((char *)platform, (char *)base_platform))
      |

Commit saved the getauxval(AT_BASE_PLATFORM) and getauxval(AT_PLATFORM)
return values in u64 which causes the compilation error.

Patch fixes this issue by changing u64 to "unsigned long".
