[][kernel][common][eth][Refactor polling idle condition of the GDM/MAC FSM]

[Description]
Refactor polling idle condition of the GDM/MAC FSM.

Designer suggests treating FSM values 0x01010000 and 0x01010100 as
MAC idle.

Without this patch, the polling idle function is unable to accurately
detect errors in the FSM.
