Production version restarting platform version field from 0 that's why add
new calculation to be able to use different DT for these platforms.
Requested DT names for production silicons for IPP/SPP and EMU platform are
versal-net-ipp-rev2.0.dts and versal-net-emu-rev2.0.dts.
If platform version increase numbers revision can be even higher.
As of today platform version is 2 that's why expected is rev2.2.

Read boodmode register using versal_net_get_bootmode() in board_late_init
and prepare corresponding distro boot command sequence based on it.
versal_net_get_bootmode() will be changed to use smc calls later, but
for now directly reads the register.

Add support for starting timer by setting up time stamp generator
registers. This is done only for EL3 i.e. mini U-Boot case.
For other cases, it will be done TF-A.
Add COUNTER_FREQUENCY and IOU_SWITCH_DIVISOR0 to Kconfig so that they
can be tuned as required.

Versal NET platform is based on Versal chip which is reusing a lot of IPs.
For more information about new IPs please take a look at DT which describe
currently supported devices.
The patch is adding architecture and board support with soc detection
algorithm. Generic setting should be very similar to Versal but it will
likely diverge in longer run.
