Use LPDDR4-100 sdram timings dtsi for RockPI-4 board.

All these timings are processed during TPL stage of rock-pi-4 board,
bootchain. This make TPL would replace rockchip in house rkbin in
current bootchain.

Bootchain after and before this change:

   TPL -> SPL -> U-Boot proper

 rkbin -> SPL -> U-Boot proper
