#1426719 — [PATCH] clk: renesas: build clk-rcar-gen2.o for R8A7792

The newly added support for R8A7792 causes build failures
because we try to call rcar_gen2_clocks_init but that is not
built into the kernel:

arch/arm/mach-shmobile/built-in.o: In function `rcar_gen2_timer_init':
:(.init.text+0x3b0): undefined reference to `rcar_gen2_clocks_init'

This changes the clk Makefile to match the other platforms, though
I guess it would be better to find another way to do this, e.g.
by not requiring the external function call by relying on
CLK_OF_DECLARE(), or by making the ARCH_RCAR_GEN2 also control
the compilation of the clk driver.

    It was in the very first patch that I submitted for this SoC:

    http://marc.info/?t=146421262300001&r=1

    It should be queued up by Geert.

There's already a similar patch in my clk-renesas-for-v4.8 branch.
