tcg/svm: use host cr4 during NPT page table walk

During a page table walk of TCG+SVM the code in target/i386/excp_helper.c
get_hphys() uses the cr4 register of the guest instead of the hypervisor
to check for the PSE bit. In the test case we have, the guest have not
enabled (yet) the PSE bit and so the page table walk results in a wrong
host physical address resolution and wrong content read by the guest.

Attached patch is against 4.2.1, but works also on 3.1.0. It fixes the
issue for our automated testcase, which is a 32bit hypervisor w/o PAE
support running a guest VM with tcg+svm.

The test worked beforehand up to qemu 2.12, started to fail with qemu 3.0
and later. The added TCG/SVM NPT commit seems to introduce the regression.

In case someone want to try to reproduce it, the iso is at [0], the good
case is [1] and the failing case is [2]. The used commandline is:

qemu-system-i386 -no-kvm -nographic -cpu phenom -m 512 -machine q35 -cdrom seoul-vmm-test.iso

target-i386: Add NPT support

This implements NPT suport for SVM by hooking into
x86_cpu_handle_mmu_fault where it reads the stage-1 page table. Whether
we need to perform this 2nd stage translation, and how, is decided
during vmrun and stored in hflags2, along with nested_cr3 and
nested_pg_mode.

As get_hphys performs a direct cpu_vmexit in case of NPT faults, we need
retaddr in that function. To avoid changing the signature of
cpu_handle_mmu_fault, this passes the value from tlb_fill to get_hphys
via the CPU state.

This was tested successfully via the Jailhouse hypervisor.

Move target-* CPU file into a target/ folder

We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.
