OPTEE_LINUXDRIVER_CLEAN_COMMON_FLAGS needs to specify the module M

This patch introduce compilation mode 32bits / 64 bits independently
for every parts:
- COMPILE_NS_USER:   Non-Secure User
- COMPILE_NS_KERNEL: Non-Secure Kernel
- COMPILE_S_USER:    Secure User
- COMPILE_S_KERNEL:  Secure Kernel

This is used on FVP, the non-secure part being bits, but the secure
part can be specified as 32 or 64 bits (64bits by default).

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).

This is the first patch of a serie that show how makefile for specific
platform support may use common rules. comon.mk is introduced. It contains:
- common variable definitions, such as the compilers
- common git to use and path (typically the OP-TEE ones)
- common macros (CCACHE, and others to come).
