rockchip/rk3399: add/remove local variables to sdram_init
This adds two local variables for dramtype and ddr_freq to sdram_init
since those two values are commonly used in the function. It also
removes a variable that is just used once and directly uses the value
for a function call instead.

BUG=none
TEST=on kevin/gru, run "stressapptest -M 1024 -s 3600" and check that
it passes
