Revision 2 is SW compatible with revision 1 but it is necessary to reflect
it in model and compatible properties which are parsed by user space.
Rev 2 has improved a power on boot reset and MIO34 shutdown glich
improvement done via an additional filter in the GreenPak chip.

SMMU is disabled by default and not all masters can be enabled at the same
time because of limited number of entries. That's why comment all iommu

Also add IDs for DP and DPDMA.

Add u-boot options node with details about bootscr-address.
c&p description from dtschema/schemas/options/u-boot.yaml:

"Holds the full address of the boot script file. It helps in making
automated flow easier by fetching the 64bit address directly from DT.
Value should be automatically copied to the U-Boot 'scriptaddr' variable.
When it is defined, bootscr-ram-offset property should be ignored.
Actually only one of them should be present in the DT."

Address is generic for all zynqmp boards because all of them have DDR
starting from 0. Custom boards should revisit the location and aligned it
based on their needs.

All si570 mgt chips have factory default 156.25MHz but DT changed it to
148.5MHz. After tracking it is pretty much c&p fault taken from Zynq
zc702/zc706 boards where 148.5MHz was setup as default because it was
requirement for AD7511 chip available on these boards.
ZynqMP board don't contain this chip that's why factory default frequency
can be used.

Now that the zynqmp pinctrl driver supports the tri-state registers, make
sure that the pins requiring output-enable are configured appropriately for
SOMs.

Without it, all tristate setting for MIOs, which are not related to SOM
itself, are using default configuration which is not correct setting.
It means SDs, USBs, ethernet, etc. are not working properly.

In past it was fixed through calling tristate configuration via bootcmd:
usb_init=mw 0xFF180208 2020
kv260_gem3=mw 0xFF18020C 0xFC0 && gpio toggle gpio@ff0a000038 && \

 "Some fixes, Some refactoring, some minor features:

   - Assorted prep work for disk space accounting rewrite

   - BTREE_TRIGGER_ATOMIC: after combining our trigger callbacks, this
     makes our trigger context more explicit

   - A few fixes to avoid excessive transaction restarts on
     multithreaded workloads: fstests (in addition to ktest tests) are
     now checking slowpath counters, and that's shaking out a few bugs

   - Assorted tracepoint improvements

   - Starting to break up bcachefs_format.h and move on disk types so
     they're with the code they belong to; this will make room to start
     documenting the on disk format better.
