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.

As recommended by Stephen Boyd, convert the Agilex/Stratix10/n5x clock
driver to use the clk_hw registration method.

Add support for Intel's eASIC N5X platform. The clock manager driver for
the N5X is very similar to the Agilex platform, we can re-use most of
the Agilex clock driver.
This patch makes the necessary changes for the driver to differentiate
between the Agilex and the N5X platforms.

For the most part the Agilex clock structure is very similar to
Stratix10, so we re-use most of the Stratix10 clock driver.

Convert, where possible, the stratix10 clock driver to the new parent
data scheme by specifying the parent data for clocks that have multiple
parents.

Just pass the clock pointer structure to the various register functions.

Add a clock driver for the Stratix10 SoC. The driver is similar to the
Cyclone5/Arria10 platforms, with the exception that this driver only uses
one single clock binding.
