Subject: [PATCH v2 1/2] spi: intel: Fix device private data and PR_NUM for Broxton controllers

Some private data fields have to change from bxt_info to cnl_info.
Here is the list of Device IDs with the respective documentation taken for
validation:
    0xa0a4 - Intel® 500 Series Chipset Family On-Package PCH
    0x02a4 - Intel® 400 Series Chipset Family On-Package PCH
    0x06a4 - Intel® 400 Series Chipset Family Platform Controller Hub
    0x34a4 - Intel® 495 Chipset Family On-Package
    0xa3a4 - Intel® B460 and H410 Chipset

According to documentation Broxton controller type has five PR registers.
