The PCIe0 instance of PCIe in J722S SoC supports:
1. 128 MB address region in the 32-bit address space
2. 4 GB address region in the 64-bit address space
The default configuration is that of a 128 MB address region in the
32-bit address space. While this might be sufficient for most use-cases,
it is insufficient for supporting use-cases which require larger address
spaces. Therefore, switch to using the 64-bit address space with a 4 GB
address region.

Since serdes0 and serdes1 are the child nodes of serdes_wiz0 and
serdes_wiz1 respectively, and, given that serdes_wiz0 and serdes_wiz1
are already disabled, it is not necessary to disable serdes0 and serdes1.
Moreover, having serdes_wiz0/serdes_wiz1 enabled and serdes0/serdes1
disabled is not a working configuration.
Hence, remove 'status = "disabled"' from the serdes0 and serdes1 nodes.

Since "serdes0" and "serdes1" which are the sub-nodes of "serdes_wiz0"
and "serdes_wiz1" respectively, have been disabled in the SoC file already,
and, given that these sub-nodes will only be enabled in a board file if the
board utilizes any of the SERDES instances and the peripherals bound to
them, we end up in a situation where the board file doesn't explicitly
disable "serdes_wiz0" and "serdes_wiz1". As a consequence of this, the
following errors show up when booting Linux:
wiz bus@f0000:phy@f000000: probe with driver wiz failed with error -12
...
wiz bus@f0000:phy@f010000: probe with driver wiz failed with error -12
To not only fix the above, but also, in order to follow the convention of
disabling device-tree nodes in the SoC file and enabling them in the board
files for those boards which require them, disable "serdes_wiz0" and
"serdes_wiz1" device-tree nodes.

It appears that pinctrl-single is misused on this SoC to control both
the mux and the input and output and bias settings. This results in
non-working pinctrl configurations for GPIOs within the device tree.
This is what happens:
(1) During startup the pinctrl settings are applied according to the
device tree. I.e. the pin is configured as output and with
pull-ups enabled.
(2) During startup a device driver requests a GPIO.
(3) pinctrl-single is applying the default GPIO setting according to
the pinctrl-single,gpio-range property.
This would work as expected if the pinctrl-single is only controlling
the function mux, but it also controls the input/output buffer enable,
the pull-up and pull-down settings etc (pinctrl-single,function-mask
covers the entire pad setting instead of just the mux field).
Remove the pinctrl-single,gpio-range property, so that no settings are
applied during a gpio_request() call.

Commit ed07d82f9e ("arm64: dts: ti: k3-am62p-j722s: Move
SoC-specific node properties") introduced the main_gpio1 node
and included the ti,ngpio property, but did not include the
gpio-reserved-ranges property. As a result, the user could try
to access gpios that do not exist. Fix this by introducing the
gpio-reserved-ranges property.
The non-existent gpios are found in the am67x datasheet [1] in Table
5-27.

The AM67A/J722S/TDA4AEN platform is a derivative of AM62P platform
and we have no single 1:1 relation regarding index of GPIO and pin
controller. The GPIOs and pin controller registers have mapping and
holes in the map. These have been extracted from the J722S data
sheet. The MCU mapping is carried forward as is with J722S, however the
main GPIO block has differences that needs to be accounted for.
Mux mode input is selected as it is bi-directional. In case a specific
pull type or a specific pin level drive setting is desired, the board
device tree files will have to explicitly mux those pins for the GPIO
with the desired setting.

J722S SoC has two instances of SERDES namely SERDES0 and SERDES1 and one
instance of PCIe namely PCIe0. Both SERDES0 and SERDES1 are single lane
SERDES. The PCIe0 instance of PCIe is a Gen3 single lane PCIe controller.
Since SERDES and PCIe are not present on AM62P SoC, add the device-tree
nodes corresponding to them in the J722S SoC specific "k3-j722s-main.dtsi"
