On A80 there are 2 watchdogs, one in the main block, and one in the
R (special) block. We do not have information on the R block watchdog,
other than the register layout is the same, and the interrupt number.
Both are able to reset the whole system.

Add the main watchdog, in case the R block is used for special purposes
like running an RTOS.

The BananaPro uses uart4 for the default rx/tx pins on the 40 pins connector,
so enable uart4.

Uart2 is also available at the bananapro io-pins, but like on the bananapi
the primary function of the pins is to act as gpios, see:

The pinctrl groups for SPI until now were also adding the chip selects in
the SPI pinctrl group.

This was causing a few issues, since a board was forced to use a random
number of chipselects, even though it might use one of these chip selects
for another pin.

The number of chipselects defined was also not the same from one group to
another because of different needs at the time these groups have been
introduced, resulting in no clear view from the board DTS on what exactly
is being muxed, which even might change in the future.

Solve this by creating different pinctrl groups for the chipselects and the
standard SPI pins (CLK, MOSI and MISO) so that we fix both issues.

with the proper compatible and add the new parent clocks.

This also adds the new pll6/4 output for pll6 on sun7i-a20. The
output is not used on sun4/5i.

Also use assigned-clocks to reparent ahb to pll6. We want ahb to
have a stable, non-changing clock rate. cpu/axi clock rate changes
as a result of newly added cpufreq support.
