6c8e97f825 Update big endian instruction encoding 
Between draft-20181101-ebe1ca4 and draft-20190622-6993896 of the
RISC-V Instruction Set Manual, the wording was changed from requiring
"natural endianness" of instruction parcels to require them to be
little endian.

Update the big endian instruction pipe to reflect the newer requirement.

65e6f6054b Add ASID field to SATP 
ASID field is missing from the SATP which causes compatibility
issues with Xous.

While this patch resolves the Xous issue, it has not been tested
on Linux.

8e466dd13c Add support for RV32E in RegFilePlugin 
The RV32E extension removes registers x16-x31 from the ISA.  This
is useful when compiling with -mem2reg to save on BRAMs.  On iCE40
HX8K this option saves 1285 LC:s, which also improves the routing
situation, when using -mem2reg.

Note that the illegal instruction exception required by the RV32E
specification for accesses to registers x16-x31 is not implemented.

f88b259eba emulator: Use external hw/common.h from LiteX 
Remove code copied from `hw/common.h` and use
the header from the LiteX repository provided
using `LITEX_BASE` environment variable.

Content of `common.h` is now evolving (new functions
are added, some are removed) and syncing it
between repos would be cumbersome.
