PCI: Make CARDBUS_MEM_SIZE and CARDBUS_IO_SIZE boot options

CARDBUS_MEM_SIZE was increased to 64MB on 2.6.20-rc2, but larger size might
result in allocation failure for the reserving itself on some platforms
(for example typical 32bit MIPS).  Make it (and CARDBUS_IO_SIZE too)
customizable by "pci=" option for such platforms.
