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/phy/initsequence: add burst chop 4 (BC4) for DDR3
...
This is needed for half rate controllers with burst length of 4.
For best efficiency quarter rate controllers should be used.
