[Buildroot] [PATCH] support/testing: test_edk2: bump ATF version to 2.9 for binutils 2.39+ support

[Romain Naour]

Following the toolchain-external-arm-aarch64 bump to version 12.2-rel1
by commit [1], binutils 2.39 is now provided by the toolchain.

This new binutils version break the ATF build due to new linker warnings as
reported by the EDK2 test:

  ld.bfd: warning: bl2.elf has a LOAD segment with RWX permissions

From [2]
"Users of GNU ld (BPF) from binutils 2.39+ will observe multiple instaces
 of a new warning when linking the bl*.elf in the form:

   ld.bfd: warning: stm32mp1_helper.o: missing .note.GNU-stack section implies executable stack
   ld.bfd: NOTE: This behaviour is deprecated and will be removed in a future version of the linker
   ld.bfd: warning: bl2.elf has a LOAD segment with RWX permissions
   ld.bfd: warning: bl32.elf has a LOAD segment with RWX permissions

 These new warnings are enbaled by default to secure elf binaries:

"

Bump the ATF custom version to 2.9 for binutils 2.39+ support.
