 * @brief Device Tree compatible clock source to Infineon PDL clock source
 *
 * This macro converts Device Tree clock source identifiers (defined in
 * ifx_clock_source_common.h) to the corresponding Infineon PDL API values.
 *
 * Usage : in clock_control_infineon_fixed_factor_clock.c, use this macro
 * when passing clock source values from Device Tree to Infineon PDL APIs.
 * This allows users to use the generic ifx_clock_source_common.h macros
 * directly in Device Tree files while ensuring compatibility with the
 * underlying PDL implementation.
