Greg Davill 6ee11edb87 phy/ecp5rgmii: Fix io delay blocks
For correct io delays in nextpnr the DEL_VALUE parameter needs to
be an integer, instead of the "DELAY{}" string.

The use of a "DELAY{}" string appears in the Lattice primitive
manual, but appears to be incorrect. At least based of the current
nextpnr.

Because we are not making use of dynamic io delays here we can
also use the simpler DELAYG block instead of DELAYF.

Fixes #50

Greg Davill 9aee36939f mac/core: Improve timing closure of core
On ECP5 targets the core struggles to meet timing closure. This
change adds buffers to the CRC module on tx/rx paths.
This results in 20-30MHz gain to max clock rate.

This fixes #47

Florent Kermarrec 0feed1720d phy/gmii/CRG: add BUFG on RX and do the TX clock Mux with combinatorial logic (from @skiphansen initial work).
This makes clocking more flexible and allows routing on more boards (ex: Pano Logic G2). Since TX clocking
does not need clock phase relationship with the input clock using a combinatorial path is fine.

For now keep it specific to ECP5, we'll integrate this soon on the others PHYs,
but some other refactoring/merging is required before.

Florent Kermarrec fb478537e7 phy/gmii: use a BUFG between eth_rx.clk and eth_rx.clk.
This makes it Xilinx specific, but without it ISE simplifies this as a single signal
(which is fine) but is not able to keep track of the "keep" attribute of both signals
and fails applying the constraints.
