MIMXRT1050_EVt: keep hyperflash_config/image_vector_table symbols in LTO builds 

Add a "used" attribute to hyperflash_config/image_vector_table to fix ARMC6 build with
the "-flto" flag.
(Error: L6236E: No section matches selector - no section to be FIRST/LAST. )

This attribute, attached to a function/variable, means that code must be emitted
for the function even if it appears that the function is not referenced.
