Mainly, ES2.1 has fixes that allow LPDDR to be used at 100% OPP (400MHz). ES2.2 additionally has a couple of power management fixes (to reduce leakage), an I2C1 SDA line state fix, and a floating point write corruption fix (cortex erratum). Even though the current mainline support doesn't need to distinguish between ES2.X versions, it's still useful to know the correct silicon rev when issues are reported. Moreover, these id checks can be used by power management code that selects suitable OPPs considering the memory speed limitation on ES2.0.
