soc/integration: Allow 0x400 CSR paging
...
It's a convenient way to get more CSR locations without changing
the whole address space layout (i.e. more space for CSR).
It still leaves 256 full 32b registers in each location which
I've never encountered a device even coming close to this, so
it should be fairly safe to do.
This doesn't change the default, just allow the user to select it.

software/liblitespi/spiflash: fix clk_freq tuning with L2 cache

Correct CRC was always calculated, regardless of divisor, as the
test flash block was in the L2 cache. This resulted in the minimum
divisor being used and incorrect flash reads with 200MHz sys_clock.
