remoteproc: stm32: fix building without ARM SMCC
When compile testing this driver without SMCC support enabled,
we get a link error:
drivers/remoteproc/stm32_rproc.o: In function `stm32_rproc_start':
stm32_rproc.c:(.text+0x776): undefined reference to `__arm_smccc_smc'
drivers/remoteproc/stm32_rproc.o: In function `stm32_rproc_stop':
stm32_rproc.c:(.text+0x92c): undefined reference to `__arm_smccc_smc'
Make the actual call to arm_smccc_smc conditional on the Kconfig
symbol controlling its implementation.
