net: hns3: add support for 1280 queues

mainline inclusion
from mainline-v5.11-rc1
commit 9a5ef4aa
category: feature
bugzilla: 173966
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=9a5ef4aa5457ceab3ad9772fa7360b34192f9463

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

For DEVICE_VERSION_V1/2, there are total 1024 queues and
queue sets. For DEVICE_VERSION_V3, it increases to 1280,
and can be assigned to one pf, so remove the limitation
of 1024.

To keep compatible with DEVICE_VERSION_V1/2 and old driver
version, the queue number is split into two part:
tqp_num(range 0~1023) and ext_tqp_num(range 1024~1279).
