    Register names for PCH P2SB device
  
    Conventions:
  
    - Register definition format:
      Prefix_[GenerationName]_[ComponentName]_SubsystemName_RegisterSpace_RegisterName
    - Prefix:
      Definitions beginning with "R_" are registers
      Definitions beginning with "B_" are bits within registers
      Definitions beginning with "V_" are meaningful values within the bits
      Definitions beginning with "S_" are register size
      Definitions beginning with "N_" are the bit position
    - [GenerationName]:
      Three letter acronym of the generation is used (e.g. SKL,KBL,CNL etc.).
      Register name without GenerationName applies to all generations.
    - [ComponentName]:
      This field indicates the component name that the register belongs to (e.g. PCH, SA etc.)
      Register name without ComponentName applies to all components.
      Register that is specific to -LP denoted by "_PCH_LP_" in component name.
    - SubsystemName:
      This field indicates the subsystem name of the component that the register belongs to
      (e.g. PCIE, USB, SATA, GPIO, PMC etc.).
    - RegisterSpace:
      MEM - MMIO space register of subsystem.
      IO  - IO space register of subsystem.
      PCR - Private configuration register of subsystem.
      CFG - PCI configuration space register of subsystem.
    - RegisterName:
      Full register name.
