soc: nxp: imxrt: fix dependencies of NXP_IMXRT_BOOT_HEADER for RT11xx

Dependencies of NXP_IMXRT_BOOT_HEADER were set incorrectly for the
RT11xx series part when building a dual core image. The boot header
should be enabled by default for the primary M7 core, and always
disabled when MCUBOOT is used or the M4 core is targeted
