soc/core: simplify/cleanup HyperRAM core
...
- rename core to hyperbus.
- change layout (cs_n with variable length instead of cs0_n, cs1_n).
- use DifferentialOutput when differential clock is used.
- add test (python3 -m unittest test.test_hyperbus).
Usage example:
from litex.soc.cores.hyperbus import HyperRAM
self.submodules.hyperram = HyperRAM(platform.request("hyperram"))
self.add_wb_slave(mem_decoder(self.mem_map["hyperram"]), self.hyperram.bus)
self.add_memory_region("hyperram", self.mem_map["hyperram"], 8*1024*1024)

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.
