We found some boards are not stable when sdram is run at 933Mhz.
Before we can fix it, we need to lower the sdram frequency to 800MHz.
In this patch we modify the DQS delay from 0x280 to 0x260 and extend
the DQS window.

This patch changes Gru SDRAM parameters from structures that just get
compiled into the romstage to individual CBFS files. This allows us to
only load the parameter set we need for the board we're booting from
flash, which reduces our boot time and the SRAM memory footprint
required to hold the romstage.

We need to enable DRAM ODT on kevin/gru board to improve the
DRAM signal. Note, if the DRAM ODT is enabled and set to 120ohms,
the sdram VREF need to adjust to 840mv.
This patch also makes following changes:
1. For compatiblity with the old board, add the
"sdram-lpddr3-hynix-4GB-666-no-odt.inc" and
"sdram-lpddr3-hynix-4GB-800-no-odt.inc" files
which do not enable sdram ODT.
2. Delete the 300MHz dram inc file. The 300MHz sdram config just
reduced 666MHz to 300MHz based on the 666MHz config file, and it is
not stable, so delete it.
3. Delete the 928MHz dram inc file, 928MHz sdram config still in
debuging, delete it for now.

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.
