fixup: generated-verilog submodule for experimental Rocket support

FIXME: This patch uses https://github.com/gsomlo/rocket-litex-verilog ,
however in the long term it would perhaps be better if enjoy-digital
hosted the generated-verilog repository.
Once that's in place, I'd be happy to re-spin (and squash) this patch
on top of its parent -- GLS

soc/cores/cpu/rocket: Support for 64-bit RocketChip (experimental)
...
Simulate a Rocket-based 64-bit LiteX SoC with the following command:
litex/tools/litex_sim.py [--with-sdram] --cpu-type=rocket
NOTE: Synthesizes to FPGA and passes timing at 50MHz on nexys4ddr
(with vivado) and ecp5versa (with yosys/trellis/nextpnr), but at
this time does not yet properly initialize physical on-board DRAM.
On ecp5versa, using '--with-ethernet', up to 97% of the available
TRELLIS_SLICE capacity is utilized.

After LiteDRAM commit #50e1d478, an additional positional argument
('databits') is required by the PhySettings() constructor.
The value used here (32) will generate a 64MByte simulated SDRAM.

When we get an error with errno 13, it means that the user doesn't
have access to the USB device. Rather than silently eating this
error and returning -1, print out a message to aid in debugging.

remote: usb: use 0x43/0xc3 for packet header

The previous value -- 0xc0 -- is used by Windows all the time to query
special descriptors. This was causing a conflict when using the USB
bridge on a Windows device.
Change the magic packet from "Vendor: Device" queries to "Vendor:
Other" by setting the bottom two bits.

soc/interconnect: remove axi_lite
...
axi_lite code was defining AXI4Lite signals and doing a AXI4Lite bridge to the
CSR bus when LiteX was not having proper AXI support. LiteX now has proper AXI
support and it also cover what axi_lite was doing: To create a AXILite to CSR
bus, user can create an AXILite2Wishbone bridge and then connect the CSR bus
directly to the wishbone bus as done in the others non-AXI SoC.
