arm64: dts: ti: k3-am62p: add opp frequencies

One power management technique available to the Cortex-A53s is their
ability to dynamically scale their frequency across the device's
Operating Performance Points (OPP)

The OPPs available for the Cortex-A53s on the AM62Px can vary based on
the silicon variant used. The SoC variant is encoded into the
WKUP_MMR0_WKUP0_CTRL_MMR0_JTAG_USER_ID register which is used to limit
the OPP entries the SoC supports. A table of all these variants can be
found in its data sheet[0] for the AM62Px processor family.

Add the OPP table into the SoC's fdti file along with the syscon node to
describe the WKUP_MMR0_WKUP0_CTRL_MMR0_JTAG_USER_ID register to detect
the SoC variant.
