We should explicitly load DTB from TFTP server or MMC/SD card
for Linux booting. This will allow us:
1. To use different Linux DTB for SiFive Unleashed board with
   expansion board connected.
2. Avoid re-flashing OpenSBI firmware whenever board connections
   change.

We should prefer accessing CSRs using their CSR numbers
because:
1. It compiles fine with older toolchains.
2. We can use latest CSR names in #define macro names of CSR
   numbers as-per RISC-V spec.
3. We can access newly added CSRs even if toolchain does not
   recognize newly added CSRs by name.

The current size allocated to U-Boot is 384k, but U-Boot has grown
to 436K which means that saving the environmental variables wipes
out part of the U-Boot source and the board ceases to function.
Due to the sector and erase size for the NOR part and a desire to
not have to change partition sizes often, this patch moves the
U-Boot environmental variables to an offset of 1M so saveenv
does not brick the board.  This patch also sets up MTDIDS and
MTDPARTS to clearly show where U-Boot and U-Boot's environmental
variables are located.

A previous patch for enabling the NAND config set a flag called
CONFIG_SKIP_LOWLEVEL_INIT when it should have been called
CONFIG_SKIP_LOWLEVEL_INIT_ONLY.  The affect this had was creating
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
"The normal CP15 init (such as enabling the instruction cache) is still
performed" per the README.  It doesn't appear to have any adverse
behavior on the SPI Flash or the NAND flash boards which use SPL.

reference clock and right input) and two output clocks (left
output and right output) in addition to a PLL mux clock which
the SERDES uses for Clock Multiplier Unit (CMU refclock).

The PLL mux clock can select from one of the three input
clocks. The right output can select between left input and
external reference clock while the left output can select
between the right input and external reference clock.

The driver has support to select PLL mux and left/right output
mux as specified in device tree.

This patch disables DM watchdog support for SPL builds and uses

The following build error is reported if DM watchdog support was
enabled in SPL:

make: *** [spl/u-boot-spl] Error 2

Adjusted WATCHDOG_RESET macro accordingly. Earlier it was pointing
to hw_watchdog_reset. Since CONFIG_WATCHDOG replaces CONFIG_HW_WATCHDOG,
now WATCHDOG_RESET macro points to watchdog_reset. This watchdog_reset
is not defined anywhere for am33xx/omap2 and needs to be defined. Fixed
this by simply calling hw_watchdog_reset in watchdog_reset.

Built and tested on AM335x device (BeagleboneBlack), compile tested for
all other AM33xx/omap2 based boards.

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.
