For TSC's precision (20~100ppm) is lower than physical RTC (less than 20ppm),
vRTC need to be calibrated by physical RTC. A timer tiggers calibration for
vRTC every 3 hours. This can improve efficiency because physical RTC can be
read once and calibrate all vRTC.

VRTC for hv used to ignore writes to vRTC register.
This patch add time modification to vRTC.
Add base RTC time and TSC offset to get the current time. Convert
current time to vRTC register values (`struct rtcdev`). Then
modify a register, and calculate a new time. Get RTC offset by
substrcting new time from current time.
Thereafter, add RTC offset also when get current time. Then user
can get the modified time.

During setting RTC time, driver will halt RTC update. So support
bit 7 of reg_b. When it set to 0, time will be updated. And
when it's set to 1, rtc will keep the second it was set.
In the process of getting RTC time, driver sets alarm interrupt,
waits 1s, and get alarm interrupt flag. So support alarm interrupt
flag update. If alarm interrupt is enabled (bit 5, reg_b set to 1),
interrupt flag register will be set (bit 7 & bit 5 of reg_c) at
appropriate time.

Add support for hour format.
Bit 1 of register B indicates the hour byte format. When it's 0,
twelve-hour mode is selected. Then the seventh bit of hour register

Current code would read physical RTC register and return it directly to guest.
This patch would read a base physical RTC time and a base physical TSC time
at initialize stage. Then when guest tries to read vRTC time, ACRN HV would
read the real TSC time and use the TSC offset to calculate the real RTC time.
This patch only support BIN data mode and 24 hour mode.
BCD data mode and 12 hour mode will add in other patch.
The accuracy of clock provided by this patch is limited by TSC, and will
be improved in a following patch also.

This patch is to fix the issue that when user edits VM name, the VM_NAME
field in IVSHMEM data doesn't sync.
To fix this, configForm emits a 'vmNameChange' when VM name is edited.
Then old name is replaced with new name. And when deleting VM, the old
name is replaced with null.
