board/qemu/aarch64-sbsa: use PARTLABEL to specify root

Browse Source 
Specifying /dev/sda2 is ambigious, and when booting my arm64 machine
this tries to mount the second partition of my ATA drive, instead of
the second partition of the USB-stick, simply because the ATA driver
is probed earlier than the USB controller driver.

To solve this problem, use PARTLABEL=root to specify the root filesystem.
This is similar to how it is currently done for board/aarch64-efi/grub.cfg
and board/qemu/aarch64-ebbr/grub.cfg.
