Subject: [PATCH 0/9] net: stmmac: cleanups and low priority fixes

Hi,

Further cleanups and a few low priority fixes:

- Remove duplicated register definitions from header files
- Fix harmless wrong definition used for PTP message type in
  descriptors
- Fix norm_set_tx_desc_len_on_ring() off-by-one error (and make
  enh_set_tx_desc_len_on_ring() follow a similar pattern.)
  Document the buffer size limits. I believe we never call
  norm_set_tx_desc_len_on_ring() with 2KiB lengths.
- use u32 rather than unsigned int for 32-bit quantities in
  descriptors
- modernise: convert to use FIELD_PREP() rather than separate mask
  and shift definitions.
- Reorganise register and register field definitions: registers
  defined in address offset order followed by their register field
  definitions.
- Remove lots of unused register definitions.
