rockchip/rk3399: provide multiple SDRAM configurations
We want to be able to easily change SDRAM clock rate for debugging
purposes. This patch adds configurations for 4 different clock rates.
Same configs are used for all rk3399 boards at 200, 666 and 800 MHz.
Kevin board does not run reliably at 666 MHz, an option for it is
added to run at 300 MHz, this option is available to Kevin only.
There is not much room left in the coreboot romstage section, this is
why the config file for 928 MHz is being added with this patch but is
not included in the code, one of the lower frequency options will have
to be dropped for the higher frequency option to be added.
BRANCH=none
BUG=chrome-os-partner:54144
TEST=run "stressapptest -M 1024 -s 3600" and pass on both kevin and
gru. Verified that on Kevin the firmware reports starting up
SDRAM at 300 MHz and on Gru at 800 MHz.
