i2c: designware: Drop hard coded FIFO depth assignment
It's not clear why the commit fe20ff5c7e9c
("i2c-designware: Add support for Designware core behind PCI devices.")
followed by commit b61b14154b19
("i2c-designware: add support for Intel Lynxpoint")
chose to hard code FIFO depth size. The FIFO depth on all hardware,
I have tested on, can be nicely detected automatically.
Thus, we may safely drop hard coded FIFO sizes from the driver.
