Added new signals to ILA to debug the RVVI tracer.

The tracer appears to be stuck and the CPU is never getting out of (into reset).

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.

Improved constraints and set ddr3 voltage to correct 1.35V. This voltage is only for synthesis. However I'm concerned because the gui did not let me select 1.35V.

Found and fixed the major architecture issue with the mig 7 used in the arty a7 board.
...
mig 7 is completely different from the ddr4 mig in that the internal pll does not general the required clocks. An external mmcm is required to general two inputs clocks and the required user clock.
