drivers: firmware: xilinx: Add unique family code for all platforms

Browse source

The family code is currently derived from the PMC_TAP_IDCODE register
value, but there are issues where Versal, Versal NET, and future
platforms share the same family code. Additionally for some platforms
have identical subfamily code, making it challenging to differentiate
between platforms based on the family and subfamily codes. To resolve
this, a new family code member is added to the platform data, initialized
with unique values. This change enables better platform distinction via
the compatible string.
