Add colorlight i5 board support

orangecrab: remove dm_remapping workaround: we are now using Wihsbone/L2 path with VexRiscv-SMP on this board.

Add board support for Terasic/Arrow SocKit, Add connectors to de0-nano

ULX3S: Make spiflash optionally accessible from the SoC, and bootable

Fix SDCard issue when no SDCard inserted in ECPIX5 board.

ECPIX-5: add option to select ECP5 device

nexys4ddr: add etherbone support

This fixes https://github.com/enjoy-digital/litedram/issues/130 and has been tested
at 48/64/96MHz on MT41K64M16 and MT41K512M16 variants.

Also remove un-needed cd_sys2x_eb.

eth-ip will also be used to configure Ethernet IP addresss.

colorlight: Add option for etherbone ip address and LED chaser

genesys2: LiteSDCard support

platforms/ecp5: Fix slewrate configuration

The SoC reset added recently creates a path between sys_clk and pll.clkin
clock domains that is reported by the tools but that can be safely ignored.

When building linux-on-litex-vexriscv for OrangeCrab:

    Warning: IOBUF 'spisdcard_clk' attribute 'SLEW' is not recognised (on line 207)
    Warning: IOBUF 'spisdcard_mosi' attribute 'SLEW' is not recognised (on line 210)
    Warning: IOBUF 'spisdcard_cs_n' attribute 'SLEW' is not recognised (on line 214)
    Warning: IOBUF 'spisdcard_miso' attribute 'SLEW' is not recognised (on line 218)

Platforms using litex.build.lattice.LatticePlatform seem to support only
"SLEWRATE", not "SLEW".  Fix the few offenders in the LogicBone and
OrangeCrab platform definitions.
