Subject: [PATCH] libretech_cc: amend boot procedure for LibreELEC
* make eMMC use MBR instead of AML partition structure
* port eMMC/SD renumbering from Hardkernel to allow booting from either SD or eMMC
* remove NAND driver (not in use)
* remove fastboot, bcb, store interface (not in use and conflicts with eMMC MBR)
* remove preboot steps that are not requried for faster booting
