Move N_CORES and MMIO_BASE to SCRFile instance in RocketChip

Provide both __OFFSET and __PADDR for SCR entries
...
This was recently changed to write out physical addresses for SCR file entries,
but to bring up the chip we need SCR offsets so we can write the uncore SCR
file over HTIF. This changes the map generator to generate both.
Without this change things happened to work anyway because the high bits were
getting dropped by the SCR file.

Allow SCR files to be enumerated in C headers
...
Right now there's no way to ensure that SCR addresses don't conflict within
RocketChip. Since upstream only has one of them this isn't a big deal, but we
want to add a whole bunch more to control all the IP on Hurricane.
This patch adds some Scala code to allocate registers inside the SCR file,
ensure they don't conflict, to provide names for SCRs, attach registers to the
SCR file, and generate a C header file that contains the addresses of every SCR
on a chip.
With this patch we'll be able to get rid of that constant in the testbench.
This also allows us to kill one of the Raven diffs, which is does pretty much
the same thing (just in a second SCR file, and hacked in).

Shift set index for multi-bank configurations
...
Prior to this commit, the L2 cache banks used the lower bits of the
block address as the set index. However, the lower bits are also used to
route addresses to different banks. As a result, in multi-bank
configurations, only a fraction of the sets in each bank could be
accessed. This commit fixes that problem by using the bits ahead of the
bank index as the set index, so that all sets in the cache can be
accessed.
