imx8mq-u-boot: Pass FIT offset to fix boot regression

Since commit 37e50627efac ("ARM: dts: imx: Convert i.MX8M flash.bin
image generation to binman") the imx8mq-evk fails to boot:

U-Boot SPL 2024.10-rc4 (Sep 09 2024 - 16:08:22 -0300)
PMIC:  PFUZE100 ID=0x10
SEC0:  RNG instantiated
Normal Boot
Trying to boot from MMC2

Fix it by passing the offset property for the FIT image, just like
it is done on i.MX8MM.
