From: Colin Ian King <colin.king@canonical.com>
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)
