Implement fdtdec_board_setup() auto-detection of ethernet PHY.
This uses properties of the hardware and pull resistor placement.
If GPIO1_16 RGMII_MDC is HIGH, then R530 (MX8MM eDM SBC) or
R390 (MX8MP eDM SBC) is populated. R530 or R390 is populated
only on boards with AR8031 PHY.
If GPIO1_16 RGMII_MDC is LOW, then the in-SoM pull down is the
dominant pull resistor. This is the case on boards with BCM54213PE
PHY.
In case AR8031 PHY is populated, the PHY MDIO address is 0, in
case BCM54213PE PHY is populated, the PHY MDIO address is 1, the
fdtdec_board_setup() is used to patch the correct address into
the U-Boot control DT.
Enable broadcom PHY support to support both PHYs.

Manorit Chawdhry <m-chawdhry@ti.com> says:
K3 devices have firewalls that are used to prevent illegal accesses to
memory regions that are deemed secure. The series prevents the illegal
accesses to ATF and OP-TEE regions that are present in different K3
devices.
AM62X, AM62AX and AM64X are currently in hold due to some firewall
configurations that our System Controller (TIFS) needs to handle.
The devices that are not configured with the firewalling nodes will not
be affected and can continue to work fine until the firewall nodes are
added so will be a non-blocking merge.

Many nodes are reused between WKUP SPL, MAIN SPL, and U-Boot. Using
bootph-pre-ram is causing these nodes to be present in SPL builds but
pruned away during the U-Boot build. Convert these nodes to bootph-all
so they will remain no matter which dtb build is happening.

Ethernet is one of a few IPs in U-Boot that depend on DMA to operate.
However there are a few missing registers ranges in the udmap nodes
need to properly setup DMA for the am65x.
A fix has been added to the Linux kernel[0] to add these ranges however
they have not made it to a Linux tag. To keep DMA operational until the
next DT sync from Linux, add these ranges to the *-u-boot.dtsi with a
note for our future selves.
