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)
