drivers/i2c/designware/dw_i2c: improve CONTROL_SPEED_FS definition
The speed control bits of the Designware I2C controller are bits 1 and 2
in the control register, so the values should be written as number
shifted by the number of the first bit. The resulting constant is
identical.
TEST=Timeless build for amd/chausie results in identical binary
