drm/i915/hwmon: Expose power1_max_interval
Expose power1_max_interval, that is the tau corresponding to PL1, as a
custom hwmon attribute. Some bit manipulation is needed because of the
format of PKG_PWR_LIM_1_TIME in
GT0_PACKAGE_RAPL_LIMIT register (1.x * power(2,y)).
v2: Update date and kernel version in Documentation (Badal)
v3: Cleaned up hwm_power1_max_interval_store() (Badal)
v4:
- Fixed review comments (Anshuman)
- In hwm_power1_max_interval_store() get PKG_MAX_WIN from
pkg_power_sku when it is valid (Ashutosh)
- KernelVersion: 6.2, Date: February 2023 in doc (Tvrtko)
v5: On some of the DGFX setups it is seen that although pkg_power_sku
is valid the field PKG_WIN_MAX is not populated. So it is
decided to stick to default value of PKG_WIN_MAX (Ashutosh)
v6: Change contact to intel-gfx (Rodrigo)
Fixed variable types in hwm_power1_max_interval_store (Andi)
Documented PKG_MAX_WIN_DEFAULT (Andi)
Removed else in hwm_attributes_visible (Andi)
