Pull morepower management updates from Rafael Wysocki:
"These update the OPP (Operating Performance Points) DT bindings for
ti-cpu (Dhruva Gole) and remove unused declarations from the OPP
header file (Zhang Zekun)"

The revision of the SoC the OPP is supported by.
53
+
This can be easily obtained from the datasheet of the
54
+
part being ordered/used. For example, it will be 0x01 for SR1.0

The eFuse bits that indicate the particular OPP is available.
58
+
The device datasheet has a table talking about Device Speed Grades.
59
+
This table is to be sorted with only the unique elements of the
60
+
MAXIMUM OPERATING FREQUENCY starting from the first row which
61
+
tells the lowest OPP, to the highest. The corresponding bits
62
+
need to be set based on N elements of speed grade the device supports.
63
+
So, if there are 3 possible unique MAXIMUM OPERATING FREQUENCY
64
+
in the table, then BIT(0) | (1) | (2) will be set, which means
65
+
the value shall be 0x7.
