Paul Mackerras c1f23e7417 litesdcard: Regenerate verilog code with buffer direction controls 
This regenerates the verilog code from upstream litex plus a patch to
generate outputs from the litesdcard module for controlling
bidirectional buffers between the FPGA and SD card.

Paul Mackerras 264e609fd4 litesdcard: Name targets by vendor.frequency, not just vendor 
In future we will want to support targets using the same vendor but
running at different clock frequencies.  Since the clock frequency is
a parameter to the gateware generation process, we now name the target
directories as "vendor.frequency", i.e., "xilinx.100e6" and
"lattice.48e6" rather than "xilinx" and "lattice".
