arm64: dts: mt7986: use size of reserved partition for bl2

To store uncompressed bl2 more space is required than partition is
actually defined.

There is currently no known usage of this reserved partition.
Openwrt uses same partition layout.

We added same change to u-boot with commit d7bb1099 [1].
