ARM: uniphier: merge board init functions into board_init()
Currently, the UniPhier platform calls several init functions in the
following order:
[1] spl_board_init()
[2] board_early_init_f()
[3] board_init()
[4] board_early_init_r()
[5] board_late_init()
The serial console is not ready at the point of [2], so we want to
avoid using [2] from the view point of debuggability. Fortunately,
all of the initialization in [2] can be delayed until [3]. I see no
good reason to split into [3] and [4]. So, merge [2] through [4].
