Parkvale is a code name, it would be better if the public name was used.

As a first step into making phylib and all PHY drivers to actually
have support for shared IRQs, make the .ack_interrupt() callback
optional.
After all drivers have been moved to implement the generic
interrupt handle, the phy_drv_supports_irq() check will be
changed again to only require the .han
This patch set aims to actually add support for shared interrupts in
phylib and not only for multi-PHY devices. While we are at it,
streamline the interrupt handling in phylib.
For a bit of context, at the moment, there are multiple phy_driver ops
that deal with this subject:
- .config_intr() - E
In preparation of removing the .ack_interrupt() callback, we must replace
its occurrences (aka phy_clear_interrupt), from the 2 places where it is
called from (phy_enable_interrupts and phy_disable_interrupts), with
equivalent functionality.
This means that clearing interrupts now becomes somethin
These functions are currently used by phy_interrupt() to either signal
an error condition or to trigger the link state machine. In an attempt
to actually support shared PHY IRQs, export these two functions so that
the actual PHY drivers can use them.

In case of a board which uses a shared IRQ we can easily end up with an
IRQ storm after a forced reboot.
For example, a 'reboot -f' will trigger a call to the .shutdown()
callbacks of all devices. Because phylib does not implement that hook,
the PHY is not quiesced, thus it can very well leave its
