Add a new SERDES driver for TI's AM654x SoC which configures
the SERDES only for PCIe. Support fo USB3 can be added later.

SERDES in am654x has three input clocks (left input, external
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 legacy omap watchdog driver on TI AM335x chipsets.

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

  CC      spl/drivers/usb/gadget/rndis.o
  LD      spl/drivers/usb/gadget/built-in.o
  LD      spl/drivers/usb/musb-new/built-in.o

make[1]: *** [spl/u-boot-spl] Error 1
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.
