Fixed a very subtle combinational loop bug the SSTC implementation of csrs.sv. STIMCMPH did not assign all XLEN bits of CSRSReadValM so dc_shell produced d-latches and vivado created a combinational loop.

Fixed lint errors for issue #368 . Does not fix simulation errors. We made a design decision a long time ago to not support DTIM on the rv32gc config because LLEN was greater than XLEN.

Modified the LSU/IFU and caches to improve critical path. Arty A7 went from 15 to 17Mhz. I believe we can push all the way to 20+Mhz with relatively little effort. Along the way I'm fixing up the scripts build the linux images for the flash card.

Wow. The newest version of Vivado does not like the enums as parameters.
...
The solution is simple. I changed the type to logic [31:0] and defined macros for the branch predictor types as 32 bit integers.

Modified bootloader to access GUID partitions. SDC interrupt to PLIC.
...
Since writing an SD card image generation script, the bootloader
needed to be altered to access individual binaries from specific
partitions. A new file, gpt.c with it's header gpt.h, have been added
to the bootloader to facilitate this.
The SDC has been added to the device tree for the VCU108
board. Additionally the SDC interrupt signal was added to the PLIC
node in the device tree. The PLIC itself was modified to accept the
SDC interrupt signal.
