meson: gxbb: change ramdisk_addr_r

0x10000000 is the start of a 2 MiB area used by the
ARM Trusted Firmware (BL31).

See
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/tree/arch/arm64/boot/dts/amlogic/meson-gx.dtsi?id=refs/tags/v4.10.10

So we should not load the ramdisk here.

The legacy Ubuntu image for the Odroid C2 comes with the
following line in boot.ini:
setenv initrd_loadaddr "0x13000000"

See
http://odroid.in/ubuntu_16.04lts/ubuntu64-16.04-minimal-odroid-c2-20160815.img.xz
http://deb.odroid.in/c2/pool/main/u/u-boot/u-boot_20170226-752a100-8_arm64.deb

So let's use the same address.

With the patch booting Linux with booti succeeds on an Odroid C2,
without the patch Linux hangs.
