Refactor the ECC code present under gp10b/, gv11b/, and tu104/. To
do this a few things were required:
Firstly, move the ecc related C and H files under the aforementioned
directories over to their new home under hal/gr/ecc/. Also copy over
the ECC HAL code present in gp10b/gp10b.c - not sure why this was
there but it, too, needed to be refactored. Also handle all the
updated header paths and Makefiles to take these movements into
account.
Secondly add a new HAL in GR (gr.ecc) to handle ECC HAL ops. There's
only two: detect and init. init() was copied over from gr and detect
was added so that the common ECC code can call it in a chip agnostic
way. This is required so that the ECC detect can be moved out of the
gp10b init characteristics function.
Lastly update the ECC init flow in the common ecc module to call
detect() right before init().
