mainboard/bap/ode_e20XX: Add different DDR3 clk settings
This patch adds two SPD files with different DDR3 clk settings.
The user can choose which setting to use.
Lower clk settings saves power under load.
SoC Model GX-411GA supports only up to DDR3-1066 clk mode.
Both SPD settings were tested with memtest for several hours.
Power saving is around half a watt under heavy memory load.
Payload SeaBIOS 1.9.1 stable, Lubuntu 16.04, Kernel 4.4.0
