[PATCH] ARM: imx: build cpuidle-imx6sx.c for imx6ul

[Anson Huang]

Fix build error when CONFIG_SOC_IMX6SX is disabled,
as i.MX6UL reuses i.MX6SX's cpuidle driver.

arch/arm/mach-imx/built-in.o: In function `imx6ul_init_late':
platform-spi_imx.c:(.init.text+0x445c): undefined reference to `imx6sx_cpuidle_init'
make: *** [vmlinux] Error 1
