[PATCH net v2 3/4] net: sparx5: fix wrong chip ids for TSN SKUs

[Daniel Machon <daniel.machon@microchip.com>]

The TSN SKUs in enum spx5_target_chiptype have incorrect IDs:

  SPX5_TARGET_CT_7546TSN    = 0x47546,
  SPX5_TARGET_CT_7549TSN    = 0x47549,
  SPX5_TARGET_CT_7552TSN    = 0x47552,
  SPX5_TARGET_CT_7556TSN    = 0x47556,
  SPX5_TARGET_CT_7558TSN    = 0x47558,

The value read back from the chip is GCB_CHIP_ID_PART_ID, which is a
GENMASK(27, 12) field, i.e. at most 16 bits wide. It can never match
these IDs, so probing a TSN part fails with a "Target not supported"
error.

Fix the enum to use the actual 16-bit part IDs returned by the
hardware: 0x0546, 0x0549, 0x0552, 0x0556 and 0x0558.
