soc: arm: nxp_imx: enable CONFIG_CACHE_MANAGEMENT for RT1xxx M7 cores

Since d992683 (soc: arm: replace redundant config option for caches for nxp_imx), RT1xxx series will not have cache enabled at boot unless CONFIG_CACHE_MANAGEMENT=y. Since this will improve performance, enable CONFIG_CACHE_MANAGEMENT by default. Signed-off-by: Daniel DeGrasse <[email protected]>
