Add bad_page_cnt_threshold to debugfs, an optional
file system used for debugging, for reporting
purposes only--it usually matches the size of
EEPROM but may be different depending on the
"bad_page_threshold" kernel module option.

The "bad_page_cnt_threshold" is a dynamically
computed value. It depends on three things: the
VRAM size; the size of the EEPROM (or the size
allocated to the RAS table therein); and the
"bad_page_threshold" module parameter. It is a
dynamically computed value, when the amdgpu module
is run, on which further parameters and logic
depend, and as such it is helpful to see the
dynamically computed value in debugfs.

Remove double-sscanf to scan for %llu and 0x%llx,
as that is not going to work!

The %llu will consume the "0" in "0x" of your
input, and the hex value you think you're entering
will always be 0. That is, a valid hex value can
never be consumed.

On the other hand, just entering a hex number
without leading 0x will either be scanned as a
string and not match, for instance FAB123, or
the leading decimal portion is scanned as the
%llu, for instance 123FAB will be scanned as 123,
which is not correct.

Thus remove the first %llu scan and leave only the
%llx scan, removing the leading 0x since %llx can
scan either.

Addresses are usually always hex values, so this
suffices.
