Subject: [PATCH 1/6] librtas: expose low-level RTAS call APIs internally

Make these functions available outside of syscall_calls.c, marking
them hidden so that they aren't exposed in the library ABI.

The implementations of librtas APIs will move into separate C files as
they gain support for new interfaces offered by the kernel.
