i2c: mv64xxx: continue probe when clock-frequency is missing
The "clock-frequency" DT property is listed as optional, However, the current code stores the return value of of_property_read_u32 in the return code of mv64xxx_of_config, but then forgets to clear it after setting the default value of "clock-frequency". It is then passed out to the main probe function, resulting in a probe failure when "clock-frequency" is missing. This patch checks and then throws away the return value of of_property_read_u32, instead of storing it and having to clear it afterwards. This issue was discovered after the property was removed from all sunxi DTs.
