[Buildroot] [PATCH] config/odroidc2: fix uboot version

[Yann E. MORIN]

The custom UBoot version was not correctly specified, causing the latest
one to be selected instead:

    /home/ymorin/dev/buildroot/buildroot/configs/odroidc2_defconfig:25:warning:
    symbol value '"2020.07"' invalid for BR2_TARGET_UBOOT_CUSTOM_VERSION

Fixes:
