  -----------
  cputlb: cleanup get_page_addr_code to use VICTIM_TLB_HIT

This replaces env1 and page_index variables by env and index
so we can use VICTIM_TLB_HIT macro later.

  Log Message:
  -----------
  cputlb: move get_page_addr_code

This just moves the code before VICTIM_TLB_HIT macro definition
so we can use it.

  -----------
  cputlb: fix the way get_page_addr_code fills the tlb

get_page_addr_code(..) does a cpu_ldub_code to fill the tlb:
This can lead to some side effects if a device is mapped at this address.

So this patch replaces the cpu_memory_ld by a tlb_fill.

  qdev: add MemoryRegion property

We need to pass a pointer to a MemoryRegion for mmio_interface.
So this just adds that.

  Log Message:
  -----------
  exec: allow to get a pointer for some mmio memory region

This introduces a special callback which allows to run code from some MMIO
devices.

SysBusDevice with a MemoryRegion which implements the request_ptr callback will
be notified when the guest try to execute code from their offset. Then it will
be able to eg: pre-load some code from an SPI device or ask a pointer from an
external simulator, etc..

When the pointer or the data in it are no longer valid the device has to
invalidate it.

  Log Message:
  -----------
  xilinx_spips: allow mmio execution

This allows to execute from the lqspi area.

When the request_ptr is called the device loads 1024bytes from the SPI device.
Then this code can be executed by the guest.
