arm: socfpga: gen5: don't zero bss in board_init_f()
The socfpga gen5 SPL manually zeroed bss in board_init_f(). Now that the
DDR driver does not use bss any more, bss is not used before board_init_r()
and we can remove this hack.
bss is normally zeroed by crt0.S, but after board_init_f(), before
board_init_r(). socfpga just had this double-zeroing because it invalidly
used bss in board_init_f() already (during DDR initialization).

a delay on startup for the NOR version which is XIP and doesn't have
SPL, so the lowlevel initialization functions need to operate.
This delay was not really noticeable at first, but the delays have been
getting longer, finally reached the point of nearly seven seconds
before the board would appear to start.
This patch sets the CONFIG_SKIP_LOWLEVEL_INIT_ONLY instead which means

watchdog: omap_wdt: Convert watchdog driver to use DT and DM
This patch adds device tree and driver model watchdog support,
converts the legacy omap watchdog driver to driver model for
TI AM335x chipsets. The following compile warning is removed:
===================== WARNING ======================
This board does not use CONFIG_WDT (DM watchdog support).
Please update the board to use CONFIG_WDT before the
v2019.10 release.
Failure to update by the deadline may result in board removal.
See doc/driver-model/MIGRATION.txt for more info.
====================================================
CONFIG_HW_WATCHDOG is no more a default option for AM33XX devices
after DT/DM conversion, adjusted kconfig accordingly.
DM watchdog support is enabled by default in SPL. The SPL image
doesn't fit into SRAM because of size constraints and build breaks
with an overflow. For this reason DM watchdog support should be
disabled in SPL, driver code should be adjusted accordingly to serve
this purpose.
Built and tested on AM335x device (BeagleboneBlack), compile tested
for all other AM33xx based boards.
The SPL for the Overo board does not initialise the MMC. Hence, it
cannot load the main boot loader from the SD card susequently. This
patch moves the initialisation code for the MMC so it gets included in
the SPL.
