Add a customizable find_distro_rootpart command to allow each board to
define its own logic for locating the rootfs partition inside the
config_distro_bootcmd logic.

Convert am335x_evm board to this new find_distro_rootpart customizable
environment variable to locate the rootfs partition dynamically, instead
of finduuid which hardcodes the rootfs partition location (mmc 0:2).
