sonic-platform-modules-cel dx010: speed up dx010 platform init script

[qnos]

• Optimize dx010 sonic platform init script to speed up init process
• Merge issue [warm-upgrade][202012] Slow Celestica platform init in rc.local causes lacp-teardown #10152: [warm-upgrade][202012] Slow Celestica platform init
  in rc.local causes lacp-teardown fix into master branch

Signed-off-by: Eric Zhu erzhu@celestica.com

Why I did it

To merge PR #10237 into master branch.
Warm upgrade causes lacp-teardown on Dx010 TOR. platform code initialize slow causing lacp timeout.

How I did it

Optimize the dx010 sonic platform script to speed up the init process.

How to verify it

• Check the warm reboot log, warm reboot is 8-9s faster than before.
