RK3399 boards like ROC-RK3399-PC is using MP8859 DC/DC converter
for 12V supply.

roc-rk3399-pc initially used 12V fixed regulator for this supply,
but the below commit has switched to use MP8859.

commit <1fc61ed04d309b0b8b3562acf701ab988eee12de> "arm64: dts: rockchip:
Enable mp8859 regulator on rk3399-roc-pc"

So, enable bydefault on the defconfig.

Can you apply this patch? w/o this regulator the default defconfig is
unable to boot the Linux.

Gentle reminder.

Jagan.
