IDE: remove ide=reverse IDE core 

This option is obsolete and can be removed safely.

It allows us to remove the pci_get_device_reverse() function from the
PCI core.

This can improve the usability of some boot managers such as lilo
when booting from a drive on an off-board controller.
If you say Y here, and you actually want to reverse the device scan
order as explained above, you also need to issue the kernel command
line option "ide=reverse". (Try "man bootparam" or see the
documentation of your boot loader (lilo or loadlin) about how to
pass options to the kernel at boot time.)
Note that, if you do this, the order of the hd* devices will be
rearranged which may require modification of fstab and other files.
