Per the workflow found in crt0.S, we don't need to clear BSS in
board_init_f nor do we need to call board_init_r since that will be
done for us from main when we return from board_init_f.

This patch removes the unneeded function calls from board_init_f.

V2:  Limit this patch to only removing unneeded function calls.

In order to call preloader_console_init from board_init_f when
DM_SERIAL is enabled, it neesd to call spl_early_init() to get early access
to DM and device tree.

This patch calls spl_early_init just before preloader_console_init()
and enables DM_SERIAL and SPL_DM_SERIAL.

V2:  Add the call to spl_early_init this patch which is requred for DM_SERIAL
