[PATCH v2 2/2] clk: renesas: r9a06g032: name anonymous structs

[Ralph Siemsen <ralph.siemsen@linaro.org>]

Clarify the content of the r9a06g032_clkdesc structure by naming the
remaining anonymous structures defined inside. Renaming each field and
updating the doc then becomes necessary in order to avoid name
duplications and kdoc warnings.
