Expose individual VRAM temperature attributes. Update Xe hwmon documentation for this entry. v2: - Avoid using default switch case for VRAM individual temperatures. - Append labels with VRAM channel number. - Update kernel version in Xe hwmon documentation. v3: - Add missing brackets in Xe hwmon documentation from VRAM channel sysfs. - Reorder BMG_VRAM_TEMPERATURE_N macro in xe_pcode_regs.h. - Add api to check if VRAM is available on the channel. v4: - Improve VRAM label handling to eliminate temp variable by introducing a dedicated array vram_label in xe_hwmon_thermal_info. - Remove a magic number. - Change the label from vram_X to vram_ch_X. v5: - Address review comments from Raag. - Change vram to VRAM in commit title and subject. - Refactor BMG_VRAM_TEMPERATURE_N macro. - Refactor is_vram_ch_available(). - Rephrase a comment. - Check individual VRAM temperature limits in addition to VRAM availability in xe_hwmon_temp_is_visible. (Raag) - Move VRAM label change out of this patch. v6: - Use in_range() for VRAM_N index check instead of if check. (Raag) - Minor aesthetic changes.
