device-purism-librem5: change default dtb when board_rev is not set (MR 1920)
According to Purism, the imx8mq-librem5.dtb alias is going away soon,
and we should be using the -r2 dtb. The -r2 dtb (which represents
Birch/Chestnut L5 variants) is most compatible, it'll boot on later
variants. dtbs for later L5 devices won't work on older devices.
