[PATCH] clk: davinci: guard da850-specific init data references

With COMPILE_TEST support, COMMON_CLK_DAVINCI can be enabled on
architectures without DaVinci support, where COMMON_CLK_DAVINCI_DA850
is not set. pll.c and psc.c unconditionally reference da850 init
functions and init data that are only built with the DA850 option,
resulting in undefined reference link errors.

Guard the da850 entries in the match tables and the CLK_OF_DECLARE
with CONFIG_COMMON_CLK_DAVINCI_DA850.
