rtc-cmos: export second NVRAM bank
Teach rtc-cmos about the second bank of registers found on most modern x86 systems, giving access to 128 bytes more NVRAM. This version only sees that extra NVRAM when both register banks are provided as part of *one* PNP resource. Since BIOS on some systems presents them using two IO resources, and nothing merges them, this can't always show all the NVRAM. (We're supposed to be able to use PNP id PNP0b01 too, but BIOS tables doesn't often seem to use that particular option.)
