Assembly functions need to be terminated with ENDPROC in order for them
to be properly annotated as functions in the object file.Change-Id: Idc8977bdc82ccaea96c09cf667c52baba0cd1969

includes: Add arm64 support
includes: Add trusty_fast_call64 api on 64 bit systems.
includes: move probe to subsys_initcall
Child devices of trusty like FIQ-based debuggers and watchdogs may
want to probe early, move trusty from module init to subsys init
to allow it and its children to probe earlier.includes: Retry std_calls on SM_ERR_BUSY
If the trusty spinlock is held, or if the strex fails for another
reason, trusty returns SM_ERR_BUSY. Add retry code to handle this.Without this retry code, std_calls can fail. If the previous smc
call had returned SM_ERR_INTERRUPTED, this failure would cause
the driver to get out of sync with trusty. All later calls would
then fail with SM_ERR_INTERLEAVED_SMC.includes: Extend smc function and move to arch specific asm file
Extend trusty smc function to pass 8 registers in both directions. Move
to separate assembly files so r7 can be used (in thumb mode r7 got
corrupted by the inline assembly even though it was specified as an
output).Change-Id: I35318be3d41f84b922397e9afdca6bf47d9645db
