rockchip/rk3399: Directly access variables in sdram.c

Browse Source 
This simplifies some of the code with better variable declaractions
which removes a lot of line continuations. Instead of declaring a
pointer to the container of the needed struct or array, this retrieves
a pointer to the struct or array instead.

BRANCH=none
BUG=none
TEST=check that gru and kevin still build and boot properly followed
by running "stressapptest -M 1024 -s 1000" and making sure it passes
