From: Tero Kristo <t-kri...@ti.com>
With the sysfw rearch, sysfw PM calls are no longer available from SPL
level. To properly support this, remove the is_on checks and the reset
assertion from the R5 remoteproc driver as these are not supported.
Attempting to access unavailable services will cause the device to hang.
