Backport PHY package MMD patch merged upstream that add support for
writing MMD regs for the PHY package and support for writing to PHY
package at an offset.

All affected patches automatically refreshed.

Subject: [PATCH 1/4] net: phy: make addr type u8 in phy_package_shared struct
Switch addr type in phy_package_shared struct to u8.
The value is already checked to be non negative and to be less than
PHY_MAX_ADDR, hence u8 is better suited than using int.

Subject: [PATCH 2/4] net: phy: extend PHY package API to support multiple
global address
Current API for PHY package are limited to single address to configure
global settings for the PHY package.
It was found that some PHY package (for example the qca807x, a PHY
package that is shipped with a bundle of 5 PHY) requires multiple PHY
address to configure global settings. An example scenario is a PHY that
have a dedicated PHY for PSGMII/serdes calibrarion and have a specific
PHY in the package where the global PHY mode is set and affects every
other PHY in the package.
Change the API in the following way:
- Change phy_package_join() to take the base addr of the PHY package
instead of the global PHY addr.
- Make __/phy_package_write/read() require an additional arg that
select what global PHY address to use by passing the offset from the
base addr passed on phy_package_join().
Each user of this API is updated to follow this new implementation
following a pattern where an enum is defined to declare the offset of the
addr.
We also drop the check if shared is defined as any user of the
phy_package_read/write is expected to use phy_package_join first. Misuse
of this will correctly trigger a kernel panic for NULL pointer
exception.

Subject: [PATCH 3/4] net: phy: restructure __phy_write/read_mmd to helper and
phydev user
Restructure phy_write_mmd and phy_read_mmd to implement generic helper
for direct mdiobus access for mmd and use these helper for phydev user.
This is needed in preparation of PHY package API that requires generic
access to the mdiobus and are deatched from phydev struct but instead
access them based on PHY package base_addr and offsets.

configure the PHY package.
Add support for these additional required function in both lock and no
lock variant.
It's assumed that the entire PHY package is either C22 or C45. We use
C22 or C45 way of writing/reading to mmd regs based on the passed phydev
whether it's C22 or C45.
