configs/avenger96_defconfig: bump ATF version to v2.8 LTS

This patch upgrades the ATF version to the v2.8 LTS version. Please note
that due to DTS changes from upstream commit
51e223058fe70b311542178f1865514745fa7874 ("feat(stm32mp15-fdts): add
Avenger96 board with STM32MP157A DHCOR SoM") The ATF additional build
variable is also modified to use the new DTS file. Note that the old DTS
file still exists, but no longer works.

Furthermore, the 'E=0' flag is removed from ATF additional build
variable. It was added by commit
deb8d71c9285eb60bc3d28e8abcf7208f78980a7 to avoid TFA build
failure because of '-Werror' flag. However, from version v2.6 or later,
it is not required anymore, the compiler warning was fixed.

The ATF patch
"board/arrow/avenger96/patches/arm-trusted-firmware/
0001-stm32mp157a-avenger96.dts-enable-hash-device-to-unbr.patch" also
has been removed. As it was not required due to using the new dhcore DTS
file for the ATF build.
