PCI: Fix unaligned accesses in VC code
The save/restore buffers for VC state is first composed of a 2-byte control
register, then a bunch of 4-byte words.
This causes unaligned accesses which trap on platform such as sparc.
This is easy to fix by simply moving the buffer pointer forward by 4 bytes
instead of 2 after dealing with the control register. The length
adjustment needs to be changed likewise as well.
Fixes: 5f8fc43217a0 ("PCI: Include pci/pcie/Kconfig directly from pci/Kconfig")
