Fix two issues with resource accounting:
1. Simba, the UltraSPARC-IIi Advanced PCI Bridge doesn't support the standard
address range registers. Skip resource accounting on these devices for now.
2. Some machines (for example sparc64) actually implement a 32-bit I/O space,
so start parsing the registers that gives us the upper 16 bits and make
sure the extent covers the entire 32-bit address range.
