Tim Lin	97cdedec80	drivers/timer: it51xxx: Compensate time calculation to reduce drift The EC timer runs at 9.2 MHz, which leads to a non-integer number of ticks per microsecond. This causes slight overestimation when delays are computed using whole ticks (e.g., using 10 ticks for 1 µs). To address this, the busy wait calculation is adjusted with a compensation factor to minimize cumulative timing error over time.

drivers/timer: it51xxx: Compensate time calculation to reduce drift

The EC timer runs at 9.2 MHz, which leads to a non-integer number of
ticks per microsecond. This causes slight overestimation when delays
are computed using whole ticks (e.g., using 10 ticks for 1 µs).
To address this, the busy wait calculation is adjusted with a
compensation factor to minimize cumulative timing error over time.

drivers/timer/it51xxx: remove not used timer

Timer 7 is not used in timer driver, which means that timer
driver doesn't initialize timer 7, it's just declared in dtsi.
So I remove it, timer 7 will be used as alarm timer for counter driver.
