w83627hf/acpi: Make `AddressMax` a multiple of `AddressAlignment`
The parallel port of the W83627HF can be configured on any port
between 0x100 and 0xFFC with 4 byte alignment for traditional modes
and 8 byte alignment for EPP mode. As the ACPI specification says
that the maximum acceptable starting address has to be a multiple
of the alignment granularity, correct the maximum starting address
from 0xFFC to 0xFF8.
