xilinx: versal-net: Add support for timer and start it
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.
