Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

Synchronize paged PHY helpers with Linux v6.17.

Add support for PHY devices that use paged register access by
implementing the following functions:
- phy_save_page(): Save current page number
- phy_select_page(): Switch to a specific page and return previous page
- phy_restore_page(): Restore previously saved page

Also adds read_page and write_page callbacks to the phy_driver
structure to enable driver-specific page handling.

These helpers allow safe access to paged PHY registers by ensuring
proper page selection and restoration,
even in error conditions, which will be used by the Airoha PHY driver.

The Auto Negotiation procedure between two Ethernet PHYs consists of
determining the best commonly supported parameters among Speed,
Duplex Mode and Flow Control.

The time taken for this procedure is not only dependent on the local
PHY used, but also on the link-partner PHY.

While a timeout can be specified in the form of a "CONFIG" on the basis
of the local PHY present on the device, since the timeout also depends
on the link-partner PHY, it might be necessary to modify the timeout.

To avoid rebuilding the bootloader for a given device, just because it
may be connected to various link-partner PHYs, each with a different
timeout, introduce an environment variable named "phy_aneg_timeout" and
override "CONFIG_PHY_ANEG_TIMEOUT" with "phy_aneg_timeout".

Remove unnecessary CL22 phy reset before ethernet phy driver
probe. Lots of ethernet phys requires driver to load firmware.
Before that, CL22 phy reset may lead to malfunction.

Switch PHY_ANEG_TIMEOUT to CONFIG_PHY_ANEG_TIMEOUT Kconfig symbol.
This removes one more configuration headers option finalizes its
Kconfig symbol conversion. No functional change expected.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Pull the PHY GPIO reset code into separate function, since
this is and will be reused multiple times. Set up default
reset assert and deassert timing to generous 20ms and 1ms
for maximum compatibility in case those DT properties are
missing.

As with fixed-link phy device, the NC-SI phy devive does not
require an mdio bus. So, a condition is added to check the
NC-SI phy id to avoid accessing the bus pointer that is NULL.
