clk: samsung: clk-s3c2410-dlck: do not use PNAME macro as it declares __initdata

The originally used PNAME macro from the core samsung clock infrastructure
declares the created array as initdata, creating section mismatch warnings
in the dclk driver.

Thus declare them directly, removing these warning.
