soc/intel/xeon_sp: Move CPU helper functions

Continue Xeon-SP de-duplication.
Move CPU helper functions from skx/ and cpx soc_util.c to common util.c.
Functions only used by util.c are updated to be static.

The following functions are moved:
 int get_threads_per_package(void);
 int get_platform_thread_count(void);
 const IIO_UDS *get_iio_uds(void);
 unsigned int soc_get_num_cpus(void);
 void get_core_thread_bits(uint32_t *core_bits, uint32_t *thread_bits);
 void get_cpu_info_from_apicid(uint32_t apicid, uint32_t core_bits,
   uint32_t thread_bits, uint8_t *package, uint8_t *core, uint8_t *thread);
 void xeonsp_init_cpu_config(void);
