Refactor common QoS code into a new common header file, and the soc specific setup_qos functions into a common API.

Rename $(soc)_qos_count and $(soc)_qos_data variables to qos_count and qos_data. When QoS settings of more SoCs are added, only one pair will be defined at a time, based on the config SOC_K3_$(soc).

This refactoring has been done for 2 major purposes.

- The auto-generated $(soc)_qos_data.c and $(soc)_qos.h files cannot have any code that is specific to any bootloader. Those files have to remain agnostic of different bootloader implementations and their header files.

- The existing implementation was less than ideal and would have enabled multiple $(soc)_qos_count and $(soc)_qos_data variables for all SoC variants.
