[PATCH v5 03/25] PM / devfreq: rockchip-dfi: use consistent name for private data struct

[Sascha Hauer <s.hauer@pengutronix.de>]

The variable name for the private data struct is 'info' in some
functions and 'data' in others. Both names do not give a clue what
type the variable has, so consistently use 'dfi'.
