[PATCH/RFC,3/6] clk: renesas: r8a7795: Mark the GPIO6 clock critical

Commit Message

Geert Uytterhoeven Feb. 9, 2018, 3:16 p.m. UTC

The GPIO6 block will be exported to a guest.  As long as the guest won't
manage its module clock, it must be kept running by the host.

TODO: Find a way to manage module clocks using PM Domains and Runtime
      PM on the guest.
