Etienne Carriere 34d743be7a package/optee-client: fix build warnings from 3.4.0
Add two patches over current optee-client 3.4.0 to fix build issues
reported by some toolchains with traces like:

  /path/to/build/optee-client-3.4.0/libteec/src/tee_client_api.c: In function 'TEEC_InitializeContext':
  /path/to/build/optee-client-3.4.0/libteec/src/tee_client_api.c:149:28: error: 'gen_caps' may be used uninitialized in this function [-Werror=maybe-uninitialized]
    ctx->reg_mem = gen_caps & TEE_GEN_CAP_REG_MEM;
                            ^
  /path/to/build/optee-client-3.4.0/libteec/src/tee_client_api.c: In function ‘TEEC_OpenSession’:
  /path/to/build/optee-client-3.4.0/libteec/src/tee_client_api.c:507:8: error: cast increases required alignment of target type [-Werror=cast-align]
    arg = (struct tee_ioctl_open_session_arg *)buf;
          ^
  /path/to/build/optee-client-3.4.0/libteec/src/tee_client_api.c: In function ‘TEEC_InvokeCommand’:
  /path/to/build/optee-client-3.4.0/libteec/src/tee_client_api.c:581:8: error: cast increases required alignment of target type [-Werror=cast-align]
    arg = (struct tee_ioctl_invoke_arg *)buf;

The optee-client patches have been in the OP-TEE project [1] & [2] and
will be available in the OP-TEE next release planned 3.5.0.

Fixes [3], [4], [5] and other failing builds reported by autobuild tests.
