integration/soc/zynq: Revert previous commit (incorrect), re-enable CSR decode on Zynq7000/MP and add check/error when SoCBusHandler has more than one Region and one of them has its decoder disabled.
...
This will prevent silent errors and means offset needs to be added in Software.

See https://github.com/enjoy-digital/litex/issues/1665 since optimizations on Shared Interconnect can't be used with
disabled decoder.

soc/software: fix i2c_write
...
commit 3fa3080e introduced an additional address length paramater to
i2c_write to support non 8bit memory addresses.
But the parameter wasn't added to the call of i2c_write in i2c_send_init_cmds.
This commit fixes the issue by adding the address length parameter to
the call of i2c_write.

cpu/rocket: rework variant naming convention
...
The naming convention for LiteX Rocket variants has become overly
complex. Simplify it while at the same time adding more flexibility.
There is a new set of instances of varying main RAM memory bus port
width (1x (64bit), 2x (128bit), 4x (256bit), and 8x (512bit)), of
each of the following principal LiteX specific Rocket models:
- small: (rv64imac, no MMU, no S, no FPU)
- medium: (rv64imac, adds MMU and S-mode)
- linux: (rv64imafdc, adds FPU, supports linux distros)
- full: (rv64imafdcbkph[+], adds hypervisor support)
NOTE: before adding H support, the feature set of the old `full`
model is now represented by the `linux` model. The old `linux`
did not use to have an FPU, and is now available as `medium`.
In addition to the range of memory port widths, each model
will be instantiated in 1, 2, 4, and 8 core variants. The
naming convention is `LitexConfig_<model>_<num_cores>_<mem_width>`.
E.g. `LitexConfig_full_8_2` for an 8-core full model with
a 128bit main RAM AXI port. On the build command line, this
example would look like:
...
--cpu-type rocket --cpu-variant full \
--cpu-num-cores 8 --cpu-mem-width 2 \
...
There are a total of 4 * 4 * 4 = 64 (sub-)variants: each of the four
principal models can be fitted with one of four core counts, and one
of four memory bus widths.

Resolves the error:
cpu/rocket/irq.h:23: Error: unrecognized opcode `csrr a4,mstatus',
extension `zicsr' required
Rocket and cva6 missed this in commit 0e2a1b54a4
as they are 64bit
CPUs, and that change only updated the 32bit CPUs.
Tested with litex_sim and riscv64-unknown-elf-ld 2.40-2+4+b1 (Debian
Bookworm).
