i2c: designware: make const array supported_speeds static to shink object code size

Don't populate const array supported_speeds on the stack, instead
make it static.  Makes the object code smaller by 150 bytes:

Before:
   text    data     bss     dec     hex filename
   8474    1440       0    9914    26ba i2c-designware-platdrv.o

After:
   text    data     bss     dec     hex filename
   8324    1440       0    9764    2624 i2c-designware-platdrv.o

(gcc version 7.2.0 x86_64)
