Andy Shevchenko 53eb64c88f platform/x86: p2sb: Don't fail if unknown CPU is found
We have accessing P2SB from a very few places for quite known hardware.

When a new SoC appears in intel-family.h it's not obvious that it needs
to be added to p2sb.c as well. Instead, provide default BDF and refactor
p2sb_get_devfn() to always succeed. If in the future we would need to
exclude something, we may add a list of unsupported IDs.

Without this change the iTCO on Intel Comet Lake SoCs became unavailable:

  i801_smbus 0000:00:1f.4: failed to create iTCO device

Fixes: 5c7b9167dd ("i2c: i801: convert to use common P2SB accessor")
