arm: dts: k3-am654-base-board: Enable wkup_i2c0 across all boot stages
To enable the use of an EEPROM-based board detection scheme we need to be able to access the I2C bus associated with the EEPROMs across all 3 stages of U-Boot: R5 SPL, A53 SPL, and A53 U-Boot (proper). So go ahead and add/update the wkup_i2c0 peripheral module DTS definitions and its associated pinmux node accordingly.
