Since commit dffdb1f8eb ("board: ti: am64x: Use fdt functions
for ram and bank init") ddr_init() and dram_bank_init() have
switched to fdtdec for getting the memory configuration from
the am64xx dts files instead of using hardcoded values. This
requires an accessible memory node in SPL as we already have
in k3-am642-r5-evm.dts.
Make the memory node accessible in A53 SPL for both am642-sk
and am642-evm and in am642-sk R5 SPL.

ROM supports cpsw_port2 for Ethernet boot and SPL stages continue to
download images on the same port, therefore there is no need to enable
cpsw_port1. Disable the same.

A Wilink wireless device is connected to MMCSD0 subsystem and is not
supported in U-Boot. Therefore, disable main_sdhci0 device tree node in
U-Boot.
If main_sdhci0 device tree node is disabled then the the index of
main_sdhci1 node becomes 0 which leads to break in boot flow. Therefore,
add an alias to fix the index to 1.

The AM64x SoC uses a central Device Management and Security Controller
(DMSC) processor that manages all the low-level device controls
including the system-wide SoC reset. The system-wide reset is managed
through the system reset driver.
Add a sysreset controller node as a child of the dmsc node to enable
the "reset" command from U-Boot prompt for the K3 AM642 SK.
