ARM: dts: qcom: Add LPDDR4x and LPDDR5 freq tables on kona

Kona supports LPDDR4x and LPDDR5 DDR types. Update the
DDR frequency tables with the supported DDR type. Also
add DDR4 and DDR5 frequency maps for the latency based
devices. The driver would check for the DDR type and
use the right frequency map at runtime.
