x1000: add dual boot helpers for the main bootloader

Two helpers (_init_clocktree and _init_uart2) already existed in
the SPL and are copied verbatim from there. The SPL versions are
still present and will be removed when dual boot works from the
main bootloader.

The other two helpers (_cleanup and _load_pdma_fw) are new.
