  target-xtensa: add window overflow check to L32E/S32E

Despite L32E and S32E primary use is for window underflow and overflow
exception handlers they are just normal instructions, and thus need to
check for window overflow.

  target-xtensa: xtfpga: attach FLASH to system IO

XTFPGA FLASH is tied to XTFPGA system IO block. It's not very important
for systems with MMU where system IO block is visible at single
location, but it's important for noMMU systems, where system IO block is
accessible through two separate physical address ranges.

Map XTFPGA FLASH to system IO block and fix offsets used for mapping.
Create and initialize FLASH device with series of qdev_prop_set_* as
that's the preferred interface now. Keep initialization in a separate
function.

  target-xtensa: implement depbits instruction

This option provides an instruction for depositing a bit field from the
least significant position of one register to an arbitrary position in
another register.

  target-xtensa: implement S32NB

S32NB provides the same functionality as S32I with two exceptions.
First, when its operation leaves the processor, the external transaction
is marked Non-Bufferable. Second, it may not be used to write to
Instruction RAM.
In QEMU S32NB is equivalent to S32I.

  Merge remote-tracking branch 'remotes/xtensa/tags/20151021-xtensa' into 
staging

Xtensa updates:

- fix register window overflow with l32e/s32e instructions;
- make MMU events logging dependent on CPU_LOG_MMU;
- attach FLASH to system I/O region on XTFPGA boards;
- implement depbits and l32nb instructions.
