Florent Kermarrec 296688b2d8 cores/jtag/ECP5JTAG: Fix LUT4's INIT to create a buffer instead of inverter, thanks @gregdavill. 
Avoid restriction to even number for tck_delay_luts.

Florent Kermarrec 0b40d78b0d cores/jtag/ECP5JTAG: Delay TCK with LUT4 to avoid sys_clk/jtag_clk relationship and support higher jtag_clk frequencies. 
Tested succesfully on the ButterStick with 75MHz sys_clk/25MHz jtag_clk.

Current tck_delay_luts is abritrary and should probably be adjusted.
