Using a phandle makes it clear which UART we are choosing without needing
to resolve through an alias first.
Especially useful for boards like the TI J721s2-EVM where the alias is
"serial2" but it actually resolves to the 8th UART instance(main_uart8).

As the binding for "current-speed" states, this should only be used
when the baud rate of an attached device cannot be detected. This is
the case for our attached on-board USB-to-UART converter used for
early kernel console. For all other unconnected/disabled ports this
can be configured in userspace later, DT is not the place for device
configuration, especially when there are already standard ways to
set serial baud in userspace.
Remove setting baud for all disabled serial ports and move setting
it for the couple enabled ports down into the board files.

MAIN_PLL0 has a flag set in DM (Device Manager) that removes it's
capability to re-initialise clock frequencies. CPTS and RGMII has
MAIN_PLL3 as their parent which does not have this flag. While RGMII
needs this reinitialisation to default frequency to be able to get
250MHz with its divider, CPTS can not get its required 200MHz with its
divider. Thus, move CPTS clock parent on J721S2 from MAIN_PLL3_HSDIV1 to
MAIN_PLL0_HSDIV6.
(Note: even GTC will be moved from MAIN_PLL3 to MAIN_PLL0 in U-Boot side
for the same reason)

There are 20 general purpose timers on j784s4 that can be used for
things like PWM using pwm-omap-dmtimer driver. There are also
additional ten timers in the MCU domain which are meant for MCU
firmware usage and hence marked reserved by default.
Though the count is similar to J721e/J7200/j721s2, the device IDs
and clocks used in j784s4 are different with the option of certain
clocks having options of additional clock muxes. Since there is very
minimal reuse, it is cleaner to integrate as part of SoC files itself.
The defaults are configured for clocking the timers from system

The odd numbered timers have the option of being cascaded to even
