dts typos in 6.1.36 and 6.1.55

[grrrr]

The file arch/arm64/boot/dts/freescale/Makefile in branches 6.1.36 and 6.1.55 currently contains

dtb-$(CONFIG_ARCH_MXC) += imx93-9x9-qsb.dtb \
                          imx93-9x9-qsb-can1.dtb \

Please note the .dts extensions for the last two files. These must be .dtb to build correctly
