Though the hip08 and the IMP(Intelligent Management Processor)
have the same byte order right now, it is better to convert
__be or __le variable into the CPU's byte order before print.

Using '%d' for printing type unsigned int or '%u' for
type int would cause static tools to give false warnings,
so this patch cleanups this warning by using the suitable
format specifier of the type of variable.
BTW, modifies the type of some variables and macro to
synchronize with their usage.

Only the queue_index field in struct hns3_nic_ring_data is
used, other field is unused and unnecessary for hns3 driver,
so this patch removes it and move the queue_index field to
hns3_enet_ring.
This patch also removes an unused struct hns_queue declaration.

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

If the input length reaches the maximum value of size_t, the reverse is
triggered when 1 is added. In addition, there is no need to have such a
large length. Therefore, the input length should be checked and the value
should be less than or equal to 1024.

This patch does following things:
1. add the keyword const before some variables which won't be modified
in functions.
2. changes some variables from signed to unsigned to avoid bitwise
operation on signed variables.
3. adds or removes initialization of some variables.
4. defines a new structure to help parsing mailbox messages instead of
using an array which is harder to get the meaning of each element.

MAC tnl interruptions are different from other type of RAS and MSI-X
errors, because some bits, such as OVF/LR/RF will occur during link up
and down.
The drivers should clear status of all MAC tnl interruption bits but
shouldn't print any message that would mislead the users.
In case that link down and re-up in a short time because of some reasons,
we record when they occurred, and users can query them by debugfs.

This patch allow users to dump content of NCL_CONFIG by using debugfs
command.
Command format:
echo dump ncl_config <offset> <length> > cmd
It will print as follows:

hns3 0000:7d:00.0: 0x0000 | 0x00000020
