[PATCH 1/2] imx8m: Enable LTO by default

From: Fabio Estevam <festevam@denx.de>

In an attempt to select ARMV8_SPL_EXCEPTION_VECTORS, the SPL size
could not fit into the internal SRAM of some imx8m targets:

aarch64: + imx8mm_phg
+aarch64-linux-ld.bfd: u-boot-spl section `__u_boot_list' will not fit in region `.sram'
+aarch64-linux-ld.bfd: region `.sram' overflowed by 1824 bytes

Select LTO to prevent that.
