Asus F2A85-M: Fix the _CRS PCI0 bus info
On Asus F2A85-M, the Linux kernel complains that the _CRS method does
not specify the number of PCI busses.
[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS
Just put there 256. This should be part of re-factoring of the whole
ACPI stuff.
The same change was already done for the AMD Brazos (SB800) boards,
based on commit »Persimmon DSDT: Add secondary bus range to PCI0«
(4733c647) [1].
