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)
