e439ed0828 configs: zynqmp: Add usb_pgood_delay for SOM boards
Add usb_pgood_delay to ensure proper detection of USB devices.
Increase the USB power good delay on the SOM boards, as this
is required for certain USB sticks otherwise, they may not
be detected.

539cf291ad zynqmp: Remove usb init initialization for Kria
USB hub initialization is done by driver introduced by commit 09f557e106ef
("usb: onboard-hub: Add i2c initialization for usb5744 hub") that's why
there is no need to do initialization via variables.

253b26a72f arm64: zynqmp: Set default RTC device at start
For RTC to start to operate there is a need to call the driver. The simple
way to do it is to set default RTC instance which will call the probe and
do basic initialization.

2f8a471231 xilinx: zynqmp: Remove conditional check for bootmenu_default variable
As per bootmenu support added default boot options to CC on AMD CCs and
default to SOM on others.
However, if no secondary boot device is enabled in the design,it should
be the default boot option for SOM when combined with AMD CCs because it
only contains SOM peripherals.
To address this issue, The conditional check for the bootmenu_default
variable was removed, and it has always been set to SOM as the default
boot option.
In this way, users can choose preferred boot options from the bootmenu
based on the boot devices configured in the design for AMD CCs.

61bf0fa866 xilinx: zynqmp: Add bootmenu support
Popup the bootmenu for 5 sec with default boot options to CC on AMD CCs and
default to SOM on others.
Users can anytime disable the bootmenu by setting the variable
enable_bootmenu=0 in zynqmp_kria.env or setup it up at run time and save
variables to NV memory.

The patch is also fixing issue created by commit 4c7363068651 ("cmd:
setexpr: fix no matching string in gsub return empty value") which has
changed return value from setexpr command (Before this commit when
matching string wasn't found command return 1 that's why was possible to
use with if).

8ef61c22cd arm64: zynqmp: Setup multiboot register to 0
On Kria when board starts from Image A or Image B partition multiboot
register is already setup to that location. When reset command is called
board is issuing soft reset which start SW at already used location (offset
of multiboot * 32k).
But board should continue to run from multiboot offset 0 (start of QSPI)
and call early bootloader every reboot that's why clear multiboot register
to 0 by default to go that route all the time.
