[Mellanox] Disable SGX for SN5600/SN5400 platforms

[vivekrnv]

Why I did it

Booting master/202405 images on SN5400 and SN5600 platforms is resulting the log

2024-07-23T21:01:07.972045+00:00 sonic kernel: [    0.110657] x86/cpu: SGX disabled by BIOS.
2024-07-23T21:01:07.972045+00:00 sonic kernel: [    0.110657] x86/cpu: SGX disabled by BIOS.

Processor on these systems supports the SGX but the BIOS does not. SGX feature is also not important and thus disable using the nosgx kernel boot parameter
