With silicon revision 2.0, add support for SD card on the am65x-evm.
Boards with silicon revision 1.0 are susceptible to interface issues
because of erratas i2025 and i2026[1] and are recommended to disable
this node.

AM654 EVM base board has TI DP83867 PHY connected to external CPSW NUSS
Port 1 in rgmii-rxid mode.
Hence, add pinmux and Ethernet PHY configuration for TI am654 SoC Gigabit
Ethernet two ports Switch subsystem (CPSW NUSS).

Add the sub-mailbox nodes that are used to communicate between MPU and
the two R5F remote processors present in the MCU domain to the AM654
EVM base board. These sub-mailbox nodes utilize the System Mailbox
clusters 0 and 1. The interrupts associated with the Mailbox Cluster
User interrupt used by the sub-mailbox nodes are also added. The GIC_SPI
interrupt to be used is dynamically allocated and managed by the System
Firmware through the ti-sci-intr irqchip driver. All the remaining
mailbox clusters are currently not used on A53 core, and so are disabled.
The sub-mailbox nodes added match the hard-coded mailbox configuration
used within the TI RTOS IPC software packages. The Cortex R5F processor
sub-system is assumed to be running in Split mode, so a sub-mailbox node
is used by each of the R5F cores. Only the sub-mailbox node from cluster 0
is used in case of Lockstep mode.

Update the power-domain cells to 2 and mark all devices as
exclusive. Main uart 0 is the debug console for based boards
and it is used by different software entities like u-boot, atf,
linux. So just mark main_uart0 as shared device for base board.

The EValuation Module(EVM) platform for AM654 consists of a
common Base board + one or more of daughter cards, which include:
a) "Personality Modules", which can be specific to a profile, such as
ICSSG enabled or Multi-media (including audio).
b) SERDES modules, which may be 2 lane PCIe or two port PCIe + USB2
c) Camera daughter card
d) various display panels
Among other options. There are two basic configurations defined which
include an "EVM" configuration and "IDK" (Industrial development kit)
which differ in the specific combination of daughter cards that are
used.
To simplify support, we choose to support just the base board as the
core device tree file and all daughter cards would be expected to be
device tree overlays.
