cores/spi: move CSR control/status to add_control method, add loopback capability and simple xfer loopback test
...
Moving control/status registers to add_control method allow using SPIMaster directly with exposed signals.
Add loopback capability (mostly for simulation, but can be useful on hardware too).

soc_core: use fixed 16MB CSR address space
...
Using too small CSR address space cause a regression on PCIe SoC, this would
need to be understood if we want to reduce CSR address space under 16MB.

soc_core: additional csr_alignment follow-up fixes
...
- Update a few additional places to use DFII_ADDR_SHIFT instead of
a hard-coded 4, which assumed 32-bit alignment.
- Force 64-bit alignment Rocket -- the only supported configuration!
This is a fixup for commit f4770219
