The booting flow is SPL -> OpenSBI -> U-Boot.
The boot hart may change after OpenSBI and may not always be hart0,
so wrap the related branch instruction with M-MODE.
Current DTB setup for XIP is not valid.
There is no chance for CONFIG_SYS_FDT_BASE, the DTB address used
in XIP mode, to be returned. Fix this.
