[Chassis] Linecards init fails if the max_cores > 16

[arlakshm]

On Arista 7800 linecards, the sai_switch_create fails with below error, if the value max_cores in the DEVICE_METADATA > 16 if the max_cores<=16 the sai_switch_create is fine.

We should support max_cores = 64. Calculation: 16 lc 2 asic per lc 2 cores per asic

Note: This issue seems to be specific to Arista. Other platforms do not have this issue.

From the error logs. this seems to be vendor independent resource issue for voqs. Looking whether there is soc property setting that is set in arista skus that would make it arista sku specific.
