The Clock Stretch Timeout (CLKT) register for the BCM2835 I2C
controller is actually located at offset 0x1c, not 0x20.
Update the BCM2835_I2C_CLKT macro to match the hardware
specification.
Since QEMU's implementation ignores whatever value the guest
writes to this register, and Linux only writes to CLKT and
doesn't read it back, the main effect of this fix is to
avoid an incorrect GUEST_ERROR log.
