The soc_device already has similar data.Why is this needed? Is it
temporary for compatibility?

struct soc_device_attribute can hold these two (product_id, and 
revision) but they are defined as char * in soc_device_atttribute, and I 
feel it's more specific for exposing via sysfs.
Also existing code in mach-exynos compares them via product_id/revision 
macros, so I can say to keep compatibility.

We had a similar discussion about the Marvell SoCs a while ago, and at
the time we concluded that it would be best to create a platform-
independent API to match the strings in soc_device_attribute against
a list of strings in the driver, either by matching the start of the
string, or using the glob_match() function. Would that work for you?
