parisc: Fix gcc 4.4 warning in lba_pci.c

Browse source 
gcc 4.4 warns about:
drivers/parisc/lba_pci.c: In function 'lba_pat_resources':
drivers/parisc/lba_pci.c:1099: warning: the frame size of 8280 bytes is larger than 4096 bytes

The problem is we declare two large structures on the stack. They don't need
to be on the stack since they are only used during LBA initialization (which
is serialized). Moving to be "static".
