net: atlantic: add AQC113 PTP traffic class and TX path setup

Browse source

Add PTP traffic class (TC) buffer reservation and TX path
improvements for AQC113:

- Reserve dedicated TX and RX buffer space for PTP TC when PTP is
  enabled, reducing user TC buffers accordingly (TX: 8KB, RX: 16KB).
- Configure PTP TC with no flow control and highest priority
  scheduling to ensure timely PTP packet transmission.

TX path improvements:
- Increase TX data and descriptor read-request limits when firmware
  has already enabled extended PCIe tag mode.

Also simplify RSS queue calculation in hw_atl2_hw_rss_set() by
extracting to a local variable and use unsigned types for loop
variables to match their usage.
