From: Arnd Bergmann <arnd@arndb.de>

The SCI reset driver can be compile testing on targets that
do not support the SCI firmware, but it fails to link when
the firmware driver is built as a module, and the reset driver
is built-in:

arm-linux-gnueabi-ld: drivers/reset/reset-ti-sci.o: in function `ti_sci_reset_probe':
reset-ti-sci.c:(.text+0x422): undefined reference to `devm_ti_sci_get_handle'

Prevent this configuration by limiting the compile test
to configurations without SCI firmware.

Fixes: a6af504184c9 ("reset: ti-sci: Allow building under COMPILE_TEST")
