The problem with detecting the FIFO depth in the platform driver is that in order to implement this we have to access the controller IC_COMP_PARAM_1 register. Currently it's done before the i2c_dw_set_reg_access() method execution, which is errors prone since the method determines the registers endianness and access mode and we can't use dw_readl/dw_writel accessors before this information is retrieved. We also can't move the i2c_dw_set_reg_access() function invocation to after the master/slave probe functions call (when endianness and access mode are determined), since the FIFO depth information is used by them for initializations. So in order to fix the problem we have no choice but to move the FIFO size detection methods to the common code and call it at the probe stage.
