[PATCH V2] i2c: designware: fix wrong tx/rx fifo for ACPI

ACPI always sets txfifo and rxfifo to 32. This configuration will cause problem if the IP core supports a fifo size of less than 32. The driver should read the fifo size from the IP and select the smaller one of the two. Signed-off-by: Tin Huynh ---
