Upstream devicetrees use a newer DT binding using cpsw-switch
compatibles. The bindings are a bit different, so two functions are
introduced to capture the differences, cpsw_eth_of_to_plat_switch() and
cpsw_eth_of_to_plat_legacy().

Use driver data to pass the correct gmii_sel function. This way new
compatibles don't need manual compatible matching as is done in
cpsw_phy_sel().

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.

Currently, the bind callback of the driver namely am65_cpsw_nuss_bind()
registers all ethernet ports including the ones that have been disabled
in the device-tree. Since the ports that have been disabled are ought to
be ignored, fix the implementation to register only the enabled ports as
indicated by their 'status' in their respective device-tree node.

The am65-cpsw driver currently sets the SEL_RGMII_IDMODE flag in a MAC's
mode register to enable or disable the TX delay. While this was supported
for earlier generations of the CPSW controller, the datasheets of all
modern TI SoCs using the am65-cpsw MAC state that the TX delay is fixed,
and the SEL_RGMII_IDMODE bit is documented as reserved in most of them.
Furthermore, while it was found that this bit does in fact disable the TX
delay, [1] states that this setting is truly unsupported by TI and not
just undocumented.

Following the clarification of the rgmii* phy-mode values in the Linux
DT bindings in [2], the Linux am65-cpsw driver was changed in [3] to
account for the fixed TX delay by fixing up the mode passed to the PHY
driver; a similar fixup already existed in the TI icssg-prueth driver.
[4] followed up on this by explicitly clearing the SEL_RGMII_IDMODE flag
to handle the case where it is set by the bootloader or other firmware
before Linux.

With the above changes, Device Trees that set the recommended "rgmii-id"
mode are now appearing in Linux 6.17+. Avoid setting the unsupported
SEL_RGMII_IDMODE flag for such Device Trees, and instead fix up the PHY
interface mode, thus aligning the U-Boot driver with the Linux kernel.

CPSW driver is defined as UCLASS_MISC driver which needs to be probed
explicitly. Define bind method for CPSW driver to scan and bind
ethernet-ports with UCLASS_ETH driver which will eventually probe CPSW
driver and avoid probing CPSW driver explicitly.
