v1 -> v2:
* Improved the calculation of addresses and masks in memory.c.

According to xHCI spec rev 1.2, unaligned access to xHCI Host
Controller Capability Registers are not prohibited. But current
implementation does not support unaligned access to 'MemoryRegion'.
These patches contain 2 changes:
1. support unaligned access to 'MemoryRegion' .
2. allow unaligned access to Host Controller Capability Registers.

Tomoyuki HIROSE (2):
  system/memory.c: support unaligned access
  hw/usb/hcd-xhci.c: allow unaligned access to Capability Registers
