gru: Make SDRAM parameters individual struct files in CBFS
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.
TEST=Booted Kevin.
