remoteproc: imx-rproc: Fix IMX_REMOTEPROC configuration

When CONFIG_IMX_REMOTEPROC is y and CONFIG_HAVE_ARM_SMCCC
is not set, compiling errors are encountered as follows:

drivers/remoteproc/imx_rproc.o: in function `imx_rproc_stop':
imx_rproc.c:(.text+0x140): undefined reference to `__arm_smccc_smc'
drivers/remoteproc/imx_rproc.o: in function `imx_rproc_detect_mode':
imx_rproc.c:(.text+0x272): undefined reference to `__arm_smccc_smc'
drivers/remoteproc/imx_rproc.o: in function `imx_rproc_start':
imx_rproc.c:(.text+0x5e0): undefined reference to `__arm_smccc_smc'

__arm_smccc_smc is defined when HAVE_ARM_SMCCC is y, so
add dependency on HAVE_ARM_SMCCC in IMX_REMOTEPROC configuration.
