rockchip/rk3399: initialize apll_b

coreboot boots from the little core, and doesn't use the big core for
now, but if apll_b is set to the default 24MHz, it will take a long time
to enable the big core.  This will cause a watchdog crash, so apll_b
initialization to 600MHz needs to be done in coreboot.

TEST=Pick CL:353762 and see big CPU clocks look right
TEST=Boot from Gru and see no cpufreq warnings
