ARM: uniphier: move lowlevel debug init code after page table switch
As the sLD3 Boot ROM has a complex page table, it is difficult to set up the debug UART with enabling it. It will be much easier to initialize the UART port after switching over to the straight-mapped page table. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
