[Buildroot] [PATCH v2 1/5] boot/optee-os: new package

OP-TEE OS is maintained by the OP-TEE project. It provides an
open source solution for development and integration of secure
services for Armv7-A and Armv8-A CPU based platforms supporting
the TrustZone technology. This technology enables CPUs to
concurrently host a secure world as the OP-TEE OS and a non-secure
world as a Linux based OS.

The OP-TEE project maintains other packages to leverage OP-TEE on
Linux kernel based OSes. An OP-TEE interface driver is available
in the Linux kernel since 4.12 upon CONFIG_OPTEE.

Changes v1 -> v2:
  - Replace dependency on BR2_arm with BR2_ARM_CPU_ARMV7 as BR2_arm
    is enabled for non Armv7 targets.
  - Correct build dependencies on OpenSSL and pycrypto.
    Remove patch on package python scripts since pycrypto dependency
    is now handled.
  - Correct location of in-tree services TAs (s/ta_services/ta/).
    Remvoe OPTEE_OS_BUILD_SERVICES as service TAs are already built built when OP-TEE OS core is built.
    Correct BR2_TARGET_OPTEE_OS_SERVICES options: it only installs the
  - Fix bad reference in Config.in package description.
  - Fix wrong hash for the optee-os v3.3.0 tarball.
  - Fix bad use of OPTEE_OS_VERSION where it is the value content that
    is expected: $(OPTEE_OS_VERSION).
  - Clarify output build directory name: use out/.
  - Minor replace use if/endif with use of depends on in Config.mk.
  - Add missing dependency of BR2_TARGET_OPTEE_OS_SERVICES
    on BR2_TARGET_OPTEE_OS_SDK.
  - Change commit header comment to "boot/optee-os: new package".
