mfd: Remove tps6586x device ID check
... and convert it to a dev_info print at probe time. There are many variants of this chip with different values of VERSIONCRC. The set of values is large, and not useful to enumerate. All are SW compatible. The difference lies in default settings of the various power rails, and other similar differences. The driver, or clients of the driver, shouldn't be affected by this, since all rails should be programmed into the desired state in all cases for correct operation.
