sdram/phy/s6ddrphy: add S6QuarterRateDDRPHY to run DDR3 at higher frequencies.
...
Built on top of S6HalfRateDDRPHY, exposes a 4 phases DFI interface to the controller with a 2x slower clock.
Validated on the Numato Lab opsis board (50MHz sys_clk/ DDR400), should also work on the Novena laptop (same DDR3 module).

sdram/phy/s6ddrphy: rename S6DDRPHY to S6HalfRateDDRPHY and use ORed wrdata_en/rddata_en (the controller already manages that)

sdram: rename self.phy_settings to self.settings (using phy.settings instead of phy.phy_settings seems cleaner)
