This patch changes the RK3328 CRU driver so it explicitly configures the CPU clock during initialization, through a call to rk3328_configure_cpu().
Previously rk3328_configure_cpu() was implemented but not called from anywhere, which I'm assuming was unintentional.
This change matches the RK3399's CRU driver (drivers/clk/rockchip/clk_rk3399.c) by
- Invoking the function at the start of rkclk_init() and - Setting the CPU clock to the lowest defined frequency, 600 MHz.
It yields no real functional change (the CPU clock is already set to 600 MHz at power-on) but it does make it straightforward to set a higher clock rate at compile time for systems like the ROCK64 that run reliably at higher frequencies.
Tested on my ROCK64.
