Geoff Levand f70557d482 powerpc/ps3_defconfig: Disable PPC64_BIG_ENDIAN_ELF_ABI_V2 
commit 482b718a84 upstream.

Commit 8c5fa3b5c4 ("powerpc/64: Make ELFv2 the default for big-endian
builds"), merged in Linux-6.5-rc1 changes the calling ABI in a way
that is incompatible with the current code for the PS3's LV1 hypervisor
calls.

This change just adds the line '# CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2 is not set'
to the ps3_defconfig file so that the PPC64_ELF_ABI_V1 is used.

Fixes run time errors like these:

  BUG: Kernel NULL pointer dereference at 0x00000000
  Faulting instruction address: 0xc000000000047cf0
  Oops: Kernel access of bad area, sig: 11 [#1]
  Call Trace:
  [c0000000023039e0] [c00000000100ebfc] ps3_create_spu+0xc4/0x2b0 (unreliable)
