alpha: fix legacy mode PCI IDE controllers

Legacy IDE resources were never properly allocated on most
alpha platforms, so IDE expectedly stopped working after
commit 10f000a2fd805e8ccfe988e8615545467bb7f7df (generic
pci_enable_resources).

Always allocate "fixed" PCI resources before doing anything else;
remove Cypress IDE quirk, as it's a generic problem which is
handled in common PCI probe code.
