package/freescale-imx/imx-seco: bump version to 3.6.3

This version is aligned with 5.4.24_2.1.0 NXP Linux BSP.
Firmware file names now include the SoC revision.

In order not to break the compatibility with the imx-seco 2.3.1
package, it remains B0 support for i.MX8QXP MEK. C0 support should
introduce a Kconfig option and this will be done in a future patch.
