meta-ti-bsp : Add build support for am62dxx-evm

The AM62D SoC is a high-performance Digital Signal Processing (DSP)
device with a quad-core Cortex-A53 cluster, dual Cortex-R5F cores, and
a Cx7 DSP core with Matrix Multiplication Accelerator (MMA). It features
a range of peripherals, including multichannel audio serial ports,
Ethernet, UARTs, SPI, I2C, USB, and more.

This SoC is part of K3-AM62x family, which includes the AM62A and AM62P
variants. While the AM62A and AM62D are largely similar, the AM62D is
specifically targeted for general-purpose DSP applications, whereas the
AM62A focuses on edge AI workloads. A key distinction is that the AM62D
does not include multimedia components such as the video encoder/decoder,
MJPEG encoder, Vision Processing Accelerator (VPAC) for image signal
processing, or the display subsystem. Additionally, the AM62D has a
different pin configuration compared to the AM62A, which impacts embedded
software development.

The EVM board is a low-cost, expandable platform designed for the AM62D2
SoC, having 4GB LPDDR4 RAM, Gigabit Ethernet expansion connectors, audio
jacks, USB ports, and more.
