Subject: configs: Add configs for AM62x SK

Add am62x_evm_r5_defconfig for R5 SPL and am62x_evm_a53_defconfig for
A53 SPL and U-Boot support.

To keep the changes to minimum. Only UART And SD boot related configs
are included. This should serve as good starting point for new board
bringup with AM62x.
