This re-enables hw_init_reset that was disabled in ea24ff6 ("liteeth_gen: improve readability and add clk_freq checks.") A chip reset is necessary using the Microchip KSZ9031RNX PHY on an antmicro-artix-dc-scm board (possibly depending on startup power timing)

Hi @mkj, sorry for the delay. The FIXME was probably here when used with the HW stack, I'll have a closer look at the use-case that was requiring it. |

I'm not sure of the original reason for this being marked FIXME, so if the
hw_init_resetneeds to remain I can instead make this a configuration option forlitedram_gen.This re-enables hw_init_reset that was disabled in
ea24ff6 ("liteeth_gen: improve readability and add clk_freq checks.")
