meta-facebook: yosemite4: Skip CXL EID establishment for T1 slots

# Description
This change optimizes the script by skipping CXL EID establishment for T1 slots
without CXL. Previously, the script would retry establishing CXL EID for
up to 10 minutes across all slot configurations, which was inefficient.

# Motivation
- Reduce unnecessary script execution time
- Prevent prolonged waiting for subsequent services
- Improve system initialization efficiency by implementing slot type check

# Test Plan
- Verified by QE team on Yosemite4 platform
- Confirmed script execution time reduced for T1 slots
- Validated no impact on other slot configurations
