[U-Boot] [PATCH 0/1] rk3328: clk: Configure CPU clock during initialization

[Simon South <simon@simonsouth.net>]

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.
