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) Signed-off-by: Colin Ian King <colin.king@canonical.com> Acked-by: Jarkko Nikula <jarkko.nikula@linux.intel.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
