Added a new ioctl to send discard commands or/and zero out
to selected data area of a regular file for security reason.
The way of handling range.len of F2FS_IOC_SEC_TRIM_FILE:
1. Added -1 value support for range.len to secure trim the whole blocks
starting from range.start regardless of i_size.
2. If the end of the range passes over the end of file, it means until
the end of file (i_size).
3. ignored the case of that range.len is zero to prevent the function
from making end_addr zero and triggering different behaviour of
the function.

Pull more power management updates from Rafael Wysocki:
"These are operating performance points (OPP) framework updates mostly,
including support for interconnect bandwidth in the OPP core, plus a
few cpufreq changes, including boost support in the CPPC cpufreq
driver, an ACPI device power management fix and a hibernation code
cleanup.

- Add support for interconnect bandwidth to the OPP core (Georgi
Djakov, Saravana Kannan, Sibi Sankar, Viresh Kumar).
- Add support for regulator enable/disable to the OPP core (Kamil
Konieczny).
