According to Kernel comment, no one checks the return value of routines:
debugfs_create_u8
debugfs_create_u16
debugfs_create_u32
debugfs_create_u64
debugfs_create_atomic_t
so remove return value of related qdf api.

For each DBR ring, add debugfs entry to dump at real-time the ring
parameters like head, tail index, the timestamps at which a buffer is
received and replenished. Issues that are specific to tail index
movement from the target can be identified with this debugfs entry.

Currently, the QDF debugfs feature returns a no-support error code for
the init call when the feature is compiled out. Instead, return success
to avoid wlan load failure on some configurations and to make error
checking by the caller more straight forward under all configurations.
The deinit call also has the same problem, but none of the callers pay
attention to the return status. Additionally, the deinit function
returns success unconditionally when the feature is compiled in.
Rather than changing the return status to success when the feature is
compiled out, change the return type of the deinit function to void.

Add qdf abstraction for debugfs APIs such as create file, create
directory, create types and remove files/directory. If a particular
operating system is not supporting debugfs or similar feature, these
API's will be a no-operation.

Add file permissions and a function to map that to Linux OS. Also
define a type for __qdf_dentry_t and __qdf_debugfs_file_t.

Create a root directory for debugfs at
/sys/kernel/debug/KBUILD_MODNAME_qdf/. The module name,
KBUILD_MODNAME, is used in the path to avoid conflict in case of
multiple instances of the same driver.
Any sub module in QDF can use this as the root directory to add
further files of directories. While unloading the driver the exit
routine does a recursive cleanup of any remaining files or
sub directories.
Even though debugfs is a Linux specific feature, a logic which is
related to file system for debugging can be added here.
This feature is protected with a compilation flag WLAN_DEBUGFS.
