xtensa: don't use a7 in simcalls
To support FRAME_POINTER avoid using a7 in __simc (none of the existing simcalls needs it). Replace calls to __simc with more specific simc_read, simc_write and simc_lseek calls. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Chris Zankel <chris@zankel.net>
