I'd like to list the support SoCs here, so in the third patch, I list
the FU740 in the description as well. I would remove the SoC names if
it is better by using a generic term. What do you think about that?

I added fu740-prci.c in the third patch, these two files fu740-prci.c
and fu540-prci.c hold the soc-dependent code, and sifive-prci.c is the
core of this driver.
