e7b55338be hw: foboot-bitstream: hardcode memory map 
Rather than relying on the memory map from litex, hardcode the
memory offsets.

This is required because sometimes the litex memory map changes,
and we want to have a consistent offset across builds.

bd08f0bb06 hw: foboot-bitstream: correct spi pin mappings for "dq" 
The "dq" mappings for SPI were wrong, and wouldn't work with the
SPI flash in dual/quad mode.  Correct these mappings for all platforms.

ee30de7946 hw: foboot-bitstream: use all 13 bits of the clock reset 
There are 13 bits on the clock reset line, but right now we only use
12 of them.  Set the counter to 8191 so we take advantage of
all 13 bits.

e1a1b60821 hw: foboot-bitstream: use GENCLK_HALF from PLL 
This removes a double-flop that we were using to get a 12 MHz clock,
which we were then multiplying back up to 48 MHz.

Fix the mapping of red, green, and blue.  Now the LEDDPWRR, LEDDPWRG,
and LEDDPWRB map to their correct values.

Additionally, a bit-banged mode for the LED has been added to enable
fine-grained control in a simpler manner.
