wl12xx: 1281/1283 support - Add Definitions

Definitions to support wl128x:
  - New FW file name
  - Chip ID
  - New PLL Configuration Algorithm macros that will be used at wl128x
    boot stage
  - Rename NVS macro name: wl127x and wl128x are using the same NVS
    file name. However, the ini parameters between them are
    different. The driver will validate the correct NVS size in
    wl1271_boot_upload_nvs().

[Cleaned up some of the definitions. -- Luca]
