Add Agilex 5 FCS and wolfBoot integration

[aidangarske]

Description

• Adds the Altera Agilex 5 013B wolfBoot port for the GSRD SD-card boot flow
• Preserves the existing SPL and TF-A responsibilities for DDR, clocks, resets, PSCI, and EL3
• Loads wolfBoot as the signed BL33 payload at 0x80200000
• Adds Agilex 5 SDHCI and platform initialization support
• Integrates signed Linux FIT images with wolfBoot verification
• Adds a four-partition WIC layout with initialized A and B image slots
• Adds Yocto/meta-wolfSSL integration, CI coverage, and customer bring-up documentation
• Validated the generated WIC through the customer Kas build and on Agilex 5 hardware

Adds an Altera Agilex 5 (013B) port and integration points to boot wolfBoot as BL33 in the GSRD SD-card flow, including SDHCI/platform init, memory mapping, example FIT artifacts, and CI build coverage.

Changes:

• Adds Agilex 5 HAL (C + header), linker script, FIT example, and a BL33 smoke-test app.
• Updates AArch64 startup/MMU mappings and SDHCI behavior to support Agilex 5 boot/SD timing.
• Updates disk-boot logging and adds docs/config + GitHub Actions build coverage for the new target.
