Daniel Golle 5096f0513b mediatek: mt7623: allow build without ext4 rootfs
The image generation code for the U7623 board expects ext4 filesystem
to be selected in menuconfig and CONFIG_TARGET_ROOTFS_PARTSIZE to be
defined. Now that ext4 isn't enabled any more, the variable was missing
and broke the build.
Set the default (104) instead of using the config variable to fix that.

# The bootrom of MT7623 expects legacy MediaTek headers present in
# exactly the location also used for the primary GPT partition table.
# (*MMC_BOOT and BRLYT)
# Hence only MSDOS/MBR partitioning can work here.

# For eMMC boot, everything up to and including the preloader must be
# written to /dev/mmcblk0boot0, with the SDMMC_BOOT header changed to
# read EMMC_BOOT\0 instead.
#
# The contents of the main eMMC are identical to the SD card layout,
# with the preloader loading 512KiB of U-Boot starting at 0x50000.
