Correct warnings flagged by checkpatch. In particular, modify
the following:
- Use octal file permissions instead of symbolic.
- Add 'const' to type of struct of_device_id variables.
- Remove unnecessary out-of-memory error messages.
- Change variables of type 'unsigned' to 'unsigned int'.
- Restructure conditionals to avoid else after return/break.
- Remove 'return' from the end of void functions.
- Correct minor whitespace inconsistencies.

Add support for configuring the memory accelerator (MEM ACC)
threshold voltage and the MEM ACC crossover voltage.
The threshold voltage is used to restrict the floor to ceiling
voltage range of all corners so that they cannot cross the
the MEM ACC threshold voltage due to CPR operation. The
crossover voltage is set when switching the MEM ACC
configuration.
If specified, the APM and MEM ACC crossover voltages are added
to the array of corners after all true corners. If both are
specified, then the APM crossover corner is added before the MEM
ACC crossover corner (i.e. last corner = MEM ACC crossover and
second to last corner = APM crossover).

threshold voltage and floor voltage less than APM threshold voltage
set an adjusted floor of max(floor, APM threshold - APM hysteresis).
