Err, sorry, the issue I get is a bit different, but similar:

arch/arm/mach-imx/built-in.o: In function `imx6q_restart':
platform-spi_imx.c:(.text+0x2220): undefined reference to `imx_src_prepare_restart'
arch/arm/mach-imx/built-in.o: In function `imx6q_pm_enter':
platform-spi_imx.c:(.text+0x22e4): undefined reference to `imx_set_cpu_jump'
arch/arm/mach-imx/built-in.o: In function `imx6q_init_irq':
platform-spi_imx.c:(.init.text+0x7280): undefined reference to `imx_src_init'
make[1]: *** [vmlinux] Error 1
