Make frequently fetched telemetry available via sysfs. These parameters
do not fit in hwmon sensor model, hence make them available via sysfs.
Create following sysfs files per acpi device node.
* c0_residency_input
* prochot_status
* smu_fw_version
* protocol_version
* ddr_max_bw(GB/s)
* ddr_utilised_bw_input(GB/s)
* ddr_utilised_bw_perc_input(%)
* mclk_input(MHz)
* fclk_input(MHz)
* clk_fmax(MHz)
* clk_fmin(MHz)
* cclk_freq_limit_input(MHz)
* pwr_current_active_freq_limit(MHz)
* pwr_current_active_freq_limit_source
