From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx> Address randconfig build issue where the linker reports an undefined reference to `r9a09g057_cpg_info`. The error occurs when CONFIG_CLK_R9A09G057 is not defined, leading to the inclusion of the device match entry without the corresponding data. By adding a preprocessor condition to the device match table, the entry for r9a09g057 is included only when CONFIG_CLK_R9A09G057 is defined, thus resolving the linker error.
