am335x-evm: Enable required dtb nodes in SPL

Browse source 
For successful boot when CONFIG_SPL_OF_CONTROL=y, we need to ensure that
the board EEPROM on i2c0, the uart0 serial port and the relevant boot
device (mmc1 or mmc2) can be accessed in the SPL. We also need to
preserve the parent nodes for each required dtb node.
