acpi: fix acpi_os_read_pci_configuration() misuse of raw_pci_read()
The raw_pci_read() interface (as the raw_pci_ops->read() before it) unconditionally fills in a 32-bit integer return value regardless of the size of the operation requested. So claiming to take a "void *" is wrong, as is passing in a pointer to just a byte variable. Noticed by pageexec when enabling -fstack-protector (which needs other patches too to actually work, but that's a separate issue).
