arm64: dts: qcom: milos: Add qfprom efuse node

Add the qfprom efuse node and describe where the GPU speedbin fuse is
located on Milos.

Note that for SM7635-AB at least, the value is "221", the max frequency
for this is 1050MHz. There's another speedbin out there for 1150MHz but
we do not know the value for it so just document in this commit.

Once the value is discovered we should add the speedbins to the A810
Adreno entry and update devicetree.
