net: phy: mscc: make some arrays static const, makes object smaller

Don't populate arrays on the stack but instead them static const.
Makes the object code smaller by 280 bytes.

Before:
   text    data     bss     dec     hex filename
  24142    4368     192   28702    701e ./drivers/net/phy/mscc/mscc_ptp.o

After:
   text    data     bss     dec     hex filename
  23830    4400     192   28422    6f06 ./drivers/net/phy/mscc/mscc_ptp.o

(gcc version 10.2.0)
