clk: ti: dpll: fix incorrect #ifdef checks

Building with W=1 shows warnings about unused const variables like this one:

drivers/clk/ti/dpll.c:99:29: error: unused variable 'omap3_dpll_core_ck_ops' [-Werror,-Wunused-const-variable]
static const struct clk_ops omap3_dpll_core_ck_ops = {};

The problem is that the #ifdef checks for some of the structures in this
file have gone out of sync with the code referencing them. Update these
to match the current usage.
