i2c: Use stable dev_name for ACPI enumerated I2C slaves
Current I2C adapter id - client address "x-00yy" based device naming scheme is not always stable enough to be used in name based matching, for instance within ALSA SoC subsystem. This is problematic in PC kind of platforms where I2C adapter numbers can change due variable amount of bus controllers, probe order, add-on cards or just because of BIOS settings. This patch addresses the problem by using the ACPI device name with "i2c-" prefix for ACPI enumerated I2C slaves. For them device name "x-00yz" becomes "i2c-INTABCD:ij" after this patch.
