Maciej W. Rozycki 9a77b8557f parport_pc: Avoid FIFO port location truncation
[ Upstream commit ab126f51c9 ]

Match the data type of a temporary holding a reference to the FIFO port
with the type of the original reference coming from `struct parport',
avoiding data truncation with LP64 ports such as SPARC64 that refer to
PCI port I/O locations via their corresponding MMIO addresses and will
therefore have non-zero bits in the high 32-bit part of the reference.
And in any case it is cleaner to have the data types matching here.
