e5d8d08981 arm64: zynqmp: Fix i2c addresses for zynqmp-p-a2197
After double checking some i2c addresses are not correct. It is visible
from i2c dump

ZynqMP> i2c dev 4
Setting bus to 4
ZynqMP> i2c mw 74 0 18

Valid chip addresses: 18 36 37 50 51 60 74
ZynqMP> i2c mw 74 0 20
ZynqMP> i2c probe
Valid chip addresses: 51 60 74

where it is clear that si570 (u5) is at 0x60 address and 8t49n240 (u39) is
also at address 0x60 based on log above.
i2c address 0x74 is i2c mux and 0x51 is eeprom.

15ca9ebb07 arm64: zynqmp: Move USB3 PHY properties from DWC3 node to USB node
Move the PHY properties from DWC3 node to USB node in ZynqMP DTs as here
the USB3 PHY used is PSGTR, which is connected to Xilinx USB core. This
PHY initialization should be handled from Xilinx USB core as the
prerequisite register configurations are done here only.

52caf2c12b arm64: zynqmp: Remove gpio from aliases list
It is not recommended to have aliases for gpio. In past it was used in
Linux for assigning numbers via sysfs which is deprecated and libgpiod
should be used instead.
In U-Boot this number is used for seq number but gpio offset are not
counted from this number. That's why having these aliases only for seq
number is not needed. As is done in Linux it is the best to use full gpio
name instead of sequence number which depends on sequence in binding.

02860e1562 zynqmp: Remove u-boot,dm-pre-reloc for uart instances
Uarts already have u-boot,dm-pre-reloc via zynqmp.dtsi that's why there is
no need to have them in platform DT files too.

3195840c94 arm64: zynqmp: Add psgtr DT descriptions
Mainline kernel has psgtr driver that's why it is good to add description
to DT files. Some boards are just missing description for USB3 and sata.
zc1751-dc1 and p-a2197 are also missing clock descriptions for input
clocks.

a34a12fabc arm64: zynqmp: Add missing silabs,skip-recall for si570 ref clk nodes
All si570 which are used for ps reference clock generation should contain
silabs,skip-recall property not to cause break on ps clock.
On Versal boards this will cause hang on Versal cpu when it is booted at
the same time with SC.
