net: hns3: expand the tc config command 

mainline inclusion
from mainline-v5.13-rc1
commit 33a8f764
category: feature
bugzilla: 173966
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=33a8f7649913e4aeda34bc1294302688112c9c56



----------------------------------------------------------------------

The device HNAE3_DEVICE_VERSION_V3 supports up to 1280 queues
and qsets for one function, so the bitwidth of tc_offset, meaning
the tqps index, needs to expand from 10 bits to 11 bits.

The device HNAE3_DEVICE_VERSION_V3 supports up to 512 queues on
one TC. The tc_size, meaning the exponent with base 2 of queues
supported on TC, which needs to expand from 3 bits to 4 bits.
