"make QEMU_VIRTFS_ENABLE=y" does not enable VirtFS because of a bad
variable name in common.mk.

Test case:

(host) echo Hello >/tmp/hello
(host) make -j8 run QEMU_VIRTFS_ENABLE=y QEMU_VIRTFS_HOST_DIR=/tmp
(QEMU) mkdir /tmp/host
(QEMU) mount_shared /tmp/host
(QEMU) cat /tmp/host/hello
Hello

Add support for configuring QEMU with VirtFS to share data
between the guest QEMU VM and host operating systems.

To specify dir, that has to be mounted inside QEMU VM, edit
QEMU_VIRTFS_HOST_DIR var in qemu.mk

To mount shared folder within QEMU ARM VM, run:
$ mount -t 9p -o trans=virtio host /tmp/shared/

If Virtfs support is enabled, libattr1-dev and libcap-dev
have to be installed before configuring QEMU.

Fixes https://github.com/OP-TEE/build/issues/28

.

In common.mk *_CLEAN_COMMON_FLAGS ?= *_COMMON_FLAGS but in the
platform makefiles (e.g. hikey.mk) they're defined as
such:
*_COMMON_FLAGS += x y z
*_CLEAN_COMMON_FLAGS += x

When expanded during a build, *_CLEAN_COMMON_FLAGS becomes
"x y z x". Variables can be repeated, which may be nothing more
than a cosmetic issue, but if any of those variables are make
targets, then 'make clean' will build them before cleaning.

To fix this, we remove the dependency of *_CLEAN_COMMON_FLAGS on
*_COMMON_FLAGS.

- Kernel config fragments that were used by the QEMU makefile are
merged into kconfigs/qemu.conf. Now, each platform has its own file
in kconfigs/
- All platforms: CONFIG_DMA_SHARED_BUFFER cannot be enabled directly
because it is  a not a visible symbol (has no prompt in Kconfig).
CONFIG_DRM is set instead which depends on DMA.
- kconfigs/hikey.conf: keep only what is necessary

The code added by commits d6536da6 ("Commonlize xtest compilation
among all platforms") and 070d9559 ("common build: optee
components") introduces race conditions that break parallel build (make
-jX). This is due to manually launching a make sub-process to run the
-common targets, and can be fixed by just declaring a dependency
instead. Specific flags are appended to common flags, rather than
passed as arguments to a new "make" sub-process.

So, basically:

 foo-common:
 	$(MAKE) -C foo_dir [A=a B=B]

 foo:
 	$(MAKE) foo-common [C=c]

is turned into:

 FOO_COMMON_FLAGS ?= A=a B=b
 foo-common:
 	$(MAKE) -C foo_dir $(FOO_COMMON_FLAGS)

 FOO_COMMON_FLAGS += C=c
 foo: foo-common

At the same time this allows foo: to override flags, for instance
set A=aa in the above example (prior to this, A=a would have had a
higher priority).
