hpt366: fix section mismatch warnings
Fix following warnings:
WARNING: o-sparc64/vmlinux.o(.data+0x195a38): Section mismatch in reference from the variable hpt37x_info.0 to the variable .devinit.data:hpt370
WARNING: o-sparc64/vmlinux.o(.data+0x195a40): Section mismatch in reference from the variable hpt37x_info.0 to the variable .devinit.data:hpt370a
WARNING: o-sparc64/vmlinux.o(.data+0x195a48): Section mismatch in reference from the variable hpt37x_info.0 to the variable .devinit.data:hpt372
WARNING: o-sparc64/vmlinux.o(.data+0x195a50): Section mismatch in reference from the variable hpt37x_info.0 to the variable .devinit.data:hpt372n
Replace a static array with a small switch resulting in
more readable code.
Mark the pci table __devinitconst.
A lot of variables are const but annotated __devinitdata.
Annotating them __devinitconst would cause a section type
conflict error when build for 64 bit powerpc.

The first patch I posted caused a section type conflict when
build for 64 bit powerpc. The actual cause of this is know and unavoidable
when we start to declare variables const.
The patch attached is much simpler as the transition from __devinitdata
to __devinitconst turned out to be bogus.
I also took the opportunity to simplify the switch as suggested by
Sergei.
