From: Arnd Bergmann <arnd@xxxxxxxx>
The rzv2g-cpg.c driver unconditionally links into the r9a09g057
one, but that may be disabled:
aarch64-linux-ld: drivers/clk/renesas/rzv2h-cpg.o:(.rodata+0x440): undefined reference to `r9a09g057_cpg_info'
Use the same approach here as with the rzg2l variant, using an #ifdef
around tha data.
I think both drivers would be better off doing the abstraction the other
way round, with the platform_driver structure defined in the most specific
file and the common bits as a library that exports common functions.
Changing it that way would require a larger rework of course.
