Add a 128M layout for the BMC flash chip we didn't boot from. Including this allows the user to write to each partition on the alternate spi chip. This dtsi follows the existing standard of using the same layout as non alt version and prepending `alt` to each partition's name.

The at25,* properties have been deprecated since 2012. These platforms weren't upstream until 2020 and 2023, so it should be safe to switch over to the "new" properties and just drop the deprecated ones.

Remove the "try-power-role = sink" property from all USB-C connectors. The try mechanism is unnecessary and wastes time during connection. Since power-role = "dual" is already configured, standard USB PD negotiation is sufficient and more efficient.

The Meta Anacapa BMC is the DC-SCM (Data Center Secure Control Module) controller for the Meta OCP Open Rack Wide (ORW) compute tray. This platform is a key component of the AMD Helios AI rack reference design system, designed for next-generation AI workloads. The BMC utilizes the Aspeed AST2600 SoC to manage the compute tray, which contains up to 4 AMD Instinct MI450 Series GPUs (connected via a Broadcom OCP NIC) and host CPUs. Its primary role is to provide essential system control, power sequencing, and telemetry reporting for the compute complex via the OpenBMC software stack.
