rockchip: rk3399: Initialize CPU B clock.

This patch sets the PLL of CPU cluster B (BPLL) to 600 MHz.
This decreases the boot time of Linux 4.19 by about 8%.

The 600 MHz are inspired by the 600 MHz used for LPLL initialization
(came in with commit 9f636a249c1).

Tested on RK3399-Q7 on Haikou base board.
