soc/cores/clock: add lock reg and assign reset
...
It was necessary to add drp_locked CSR for reading LOCK signal from
MMCM. Additionally, input signal RESET from MMCM was not driven by
any signal to do a proper reset of MMCM module thus it was impossible
to perform entirely correct dynamic clock reconfiguration.

soc_sdram, bios/sdram: support sdram init for csr_data_width <= 32
...
Enable SDRAM to be initialized when csr_data_width > 8 bits.
Currently, csr_data_width up to 32 bits is supported.
Read leveling tested with csr_data_width [8, 16, 32] on the
ecp5-versa5g and trellisboard (using yosys/trellis/nextpnr),
and on the nexys4ddr (using Vivado).

With high speed link (10gbps XGMII ethernet for example), stream data_width is generally
> 8-bit which make header/data un-aligned on bytes boundaries. The change allows the
Packetizer/Depacketizer to work on stream with a data_width > 8-bit.

cpu/rocket: parameterize axi interface data width
...
Rocket variants can be configured with axi port data widths that
are multiples of the native word size (64 bits in our case). In
the future, we will add variants with mem_axi data width > 64 bit,
to match the native data width of the LiteDRAM controller on
various development boards (e.g., 128 bits on the ecp5versa, and
256 bits on the trellisboard).

cpu/rocket, soc_sdram: Connect mem_axi to LiteDRAM, bypass WB bus
...
Connect Rocket's dedicated port for cached RAM accesses (mem_axi)
directly to the LiteDRAM data port, bypassing the shared LiteX
(Wishbone) bus.
When both Rocket's mem_axi and LiteDRAM's port have the same data
width, use a native point-to-point AXI connection.
Otherwise, convert both ends to Wishbone, and use the Wishbone
data width converter to bridge the gap.
FIXME: In the future, this part should be replaced with a native
AXI data width converter!
