fix(zynqmp): workaround issue around cntpct_el0
cntvct_el0 after power up has an architecturally UNKNOWN value.
In ZynqMP case the value is very high (e.g. 0xefffffe80d4de62d).
At best value should be 0 because it is used for time measuring when
systemd analyze command is called (via storing it in UEFI variables).
As a workaround for this issue use cntvoff_el2 to record offset from actual value which clears cntvct_el0.
There could be different way how to achieve this behavior but till that
time use this workaround to fix systemd analyze behavior.
