drm/i915/hwmon: Expose card reactive critical power
Expose the card reactive critical (I1) power. I1 is exposed as
power1_crit in microwatts (typically for client products) or as
curr1_crit in milliamperes (typically for server).
v2: Add curr1_crit functionality (Ashutosh)
v3: Use HWMON_CHANNEL_INFO to define power1_crit, curr1_crit (Badal)
v4: Use hwm_ prefix for static functions (Ashutosh)
v5: KernelVersion: 6.2, Date: February 2023 in doc (Tvrtko)
v6: Change contact to intel-gfx (Rodrigo)
