during build (clang and clang+debug).

High resolution timer can now be excluded from the build.
There is currently no HR Timer implementation for other
platform than HiSi.

Note: HR Timer will be enabled by default

The macros assume that constants that are compared against
"addr" are either unsigned or less than INT_MAX.
In some cases it is not true so change costants to unsigned
using U32_C macros.
The correct solution would be to change teh MEM_ADDR, PMM_BASE, etc.
to be unsigned long but currently "U" suffix is appended in various
places so the assumption is that those macros use default definition
(which is int).

Put "addr" into brackets by the way since it could be an expression
rather than one variable.

The macro to append "U" suffix should be named
according to what it actually does which is defining U32 constant.

For some reason more brackets is worse than no brackets
and warning is generated that is threated as error.
Therefore remove brackets to fix the build when
LOSCFG_PLATFORM_ROOTFS is defined

Minimal system configuration for Qemu ARM Virtual platform
based on Cortex-A7, with GICv2.

Some debugging options are enabled to allow for shell bring-up,
hence debug configuration type.

Mainly adding missing headers, removing redundant headers that
induce undefined symbols or rearranging existing headers
according to dependencies betheen them.
Also add missing include paths to makefiles and make configs.

Note: direct inclusion of pthread.h in disk.h is caused by the
latter being used almost everywhere, including third_party libraries.
Putting pthread.h there releases us from affecting more code.

Basically fixes build for anything that is not default HiSi
configuration.

If the platform doesn't support rootfs but shell and serial
console are enabled, create Shell task in kernel.
Note that normally, shell task is created by /bin/init.

BSD compatibility is not optional for the kernel to build, however
platform dependent portion of this configuration, machine_resource_init(),
which is called by nexus_init() is implemented only in the platform
specific library for HiSilicon chips (libhi35xx_bsp.a).
Workaround lack of this library, so that the kernel can be built
for other platforms as well, by excluding it from the compilation.

This change should be removed as soon as the appropriate function
is implemented for other platforms.

During LiteOS consolidation, system_init.o object that contains
SystemInit() doesn't exist yet as it is being built later
and linked in ./vendor directory when OHOS_Image is created.
This is not the case when building for HiSilicon platforms as
SystemInit is provided for them in precompiled libraries.

Workaround this issue by creating "weak" function in LiteOS
that will be replaced by the "strong" symbol from ./vendor
in linking phase of the OHOS_Image.
