Subject: [PATCH] [Mellanox] Update SN5640-simx enabled processes (#21478)

- Why I did it
Support running hw-management service on SN5640 emulation platform.

- How I did it
Use physical EEPROM instead of the fake one
Do not skip PSUd, PCId, thermal control daemon
Adjust PCIe and thermal configuration files

- How to verify it
Run Nvidia simulation on SN5640 (ASIC and Platform)
