acrn: test case of kernel.timer and kernel.timer.tickless failed

[enjiamai]

Describe the bug
Test case kernel.timer.kernel.timer.timeout_abs and
Test case kernel.timer.kernel.timer.tickless.timeout_abs falied in ACRN EHL CRB

To Reproduce
Steps to reproduce the behavior:

1. Make sure BIOS configuration is correct for ACRN, and include/arch/x86/memory.ld line 44, LOCORE_BASE modified from 0x1000 to 0x8000.
2. Run this command from the zephyrproject:
3. twister -p acrn_ehl_crb --device-testing --device-serial-pty="/opt/remotehw/acrn-test-pty.exp,ehlsku11" --west-flash="/opt/remotehw/remotehw-x86-acrn.sh,ehlsku11" -vv -T tests/kernel/interrupt
4. Check handler.log in twister.out in directory to see the error log.

Expected behavior
The test case is passed as expected.

Impact
ACRN on ehl_crb platform has little lower pass rate.
