arm64: dts: ti: k3-am62a-phycore-som: Add 1.4GHz opp entry

Browse Source 
The phyCORE-AM62Ax is capable of supplying 0v85 to the VDD_CORE
which allows the Cortex-A53s to operate at 1.4GHz according to chapter
7.5 of the SoC's data sheet[0]. Append the 1.4Ghz entry to the OPP table
to enable this OPP
