[PATCH] mach-imx: bootaux: fix building with disabled bootelf

[Oleksandr Suvorov]

If CMD_ELF disabled and IMX_BOOTAUX enabled, the u-boot building ends
up with a linking error [1]. Select LIB_ELF for all cases when
valid_elf_image() is used in the imx_bootaux module.

[1]
ld: /tmp/ccaF1rpv.ltrans0.ltrans.o: in function `do_bootaux':
arch/arm/mach-imx/imx_bootaux.c:108: undefined reference to `valid_elf_image'

Fixes: c0f037f6a2a ("mach-imx: bootaux: elf firmware support")
