MIPS: generic: Support booting with built-in or appended DTB
The plat_get_fdt() checked that the kernel was booted using UHI before
reading the 'fw_passed_dtb' variable. However, this variable is also set
when the DT has been appended, or when it has been built into the kernel.
Support these usecases by removing the UHI check.
