Each of these clocks(s2f_usr0/1, sdmmc_clk, gpio_db, emac_ptp, emac0/1/2) have a bypass setting that can use the boot_clk. The previous representation was not correct.

Fix the representation.

The EMAC clocks on Stratix10/Agilex/N5X have an additional bypass that was not being accounted for. The bypass selects between emaca_clk/emacb_clk and boot_clk.

Because the bypass register offset is different between Stratix10 and Agilex/N5X, it's best to create a new function to calculate the bypass.

If the bypass_reg is set, then we can return the bypass parent, however, if there is not a bypass_reg, we need to figure what the correct parent mux is.

The previous code never handled the parent mux if there was a bypass_reg.
