firmware: arm_scmi: Cleanup unused core transfer helper wrappers
Remove unused core scmi_xfer wrappers now that we have migrated all protocols to the new interface based on protocol handles. Link: https://lore.kernel.org/r/20210316124903.35011-34-cristian.marussi@arm.com Tested-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Cristian Marussi <cristian.marussi@arm.com> Signed-off-by: Sudeep Holla <sudeep.holla@arm.com>
