This fixes a bug introduced by commit 4334e8d. In ta_dev_kit.mk, out-dir must
be set to '.' and not left empty when output directory (O=) is not specified.
Otherwise, when building a trusted app, the compile rule will have an unwanted
leading slash (result from the expansion of $(out-dir)/$(...) in compile.mk).
Error is:

Cosmetic fixes for build output

By default, the OP-TEE build shows abbreviated output similar to the Linux
kernel. This commit fixes a number of deviations/inconsistencies.

- Always print a command in uppercase, followed by the target file.
- Make sure commands and file paths are nicely aligned, with two leading spaces
to make command output/errors better stand out.
- Remove some duplicate slashes in file paths. We use the following rule:
variables that hold directory names such as $(arch-dir) or $(platform-dir)
always have a trailing slash. The 'subdirs' and 'incdirs' variables used in
sub-makefiles are an exception because doing otherwise would needlessly
clutter the sub-makefiles.

mk/compile.mk: simplify dependency generation; better support ccache

This commit modifies the compilation flags that are used to generate
dependency files (*.o.d). Rather than using the preprocessor's -MD flag
(-Wp,-MD,<depfile>), we now use the frontend's equivalent (-MD -MF <depfile>
-MT <target>).

There are three reasons for doing so:
1. The GCC man page recommends against using -Wp, because "the
preprocessor's direct interface is undocumented and subject to change".
2. The new flags generate the correct rule directly, including the
subdirectory in front of the object name, so scripts/fixdep is not needed
anymore.
3. ccache (3.1.9) would not handle -Wp,-MD as expected. It would preserve
the directory prefix, so that we would end up with an invalid path after
the fixdep phase, making the rules useless. With this patch, OP-TEE builds
fine with ccache:
make -j3 CROSS_COMPILE="ccache arm-linux-gnueabihf-"

Cleanup loading/unloading of a TA

* A TA is only loaded via tee-supplicant, directly supplying a

This requires and update to the client lib to avoid leaking

TA have been loaded into secure memory
* Divides tee_ta_init_session() into sevaral functions
* Divides tee_ta_close_session() into two functions
* Divides tee_ta_load() into several functions with one

* Removes some unused code for kernel TAs
* Removes the option to lock/unlock a TA is only used by kernel
TAs which we don't support any longer.

Align interface between TEE and secure monitor with the interface

Uses an ATF compatible entry vector for entering TEE from internal

Internal secure monitor saves entry reason to be able to tell when
switching back to nonsecure world if r0-r3 should be preserved (FIQ case)
or returned as is (normal call case).
