'@100' of here, I make up the address by get from bus 1, device 0,
function 0.
Such as below '@200' means bus 2, device 0, function0.
That is not how PCI unit addresses are encoded. There are
two forms: bla@D and bla@D,F where D and F are device# and
function# respectively. The bus# is implicit from the
parent node.
You have the "reg" property wrong, too (but differently).
