arm/linux-yocto: disable CONFIG_MTD_NAND_FSL_IFC

Linux stable kernel v5.15.166 added commit e59386c300198385d8bf33336de3b8c165d20d00,
which modifies the depends for the Freescale IFC NAND controller.  See
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.15.y&id=e59386c300198385d8bf33336de3b8c165d20d00

Because of this change, do_kernel_configcheck is logging an warning
about values not matching.  To address this issue, disable it manually
in a config fragment, but only for the affected machines in meta-arm.
