Pull request overview

This PR adds dedicated board support for the Curtiss-Wright VPX3-152 board targeting the NXP T2080 platform. Previously, the VPX3-152 shared configuration with the T2080 RDB default; this PR separates them with board-specific settings confirmed from U-Boot hardware dumps.

Changes:

• Adds board-specific DDR3L memory configuration (4GB single-rank) and DDR register values for the CW VPX3-152, splitting it from the T2080 RDB defaults.
• Configures 256MB NOR flash support for the VPX3-152 (vs. 128MB on the RDB), including flash base address, LAW size, and TLB page size.
• Updates the example config file with commented-out CW VPX3-152 flash address alternatives and documents the board differences.
