[U-Boot] [PATCH 07/10] rockchip: puma-rk3399: update board_init()

The original initialisation code for board_init() was largely lifted
from the code on the EVB. However, the RK3399-Q7 can do with a much
more concise init sequence.
This cleans up the board_init() by updating it to the essentials for
the RK3399-Q7 and getting rid of the accumulated cruft.
