fix(rockchip): align fdt buffer on 8 bytes

Since commit 94b2f94bd632 ("feat(libfdt): upgrade libfdt source files"),
8-byte alignment of the FDT address is enforced to follow the DT
standard.

Rockchip implementation of params_early_setup loads the FDT address as
passed by the bootloader into a buffer. This buffer is currently made of
uint8_t which means it is not 8-byte aligned and might result in
fdt_open_into failing.

Instead, let's make this buffer uint64_t to make it 8-byte aligned.
