In certain HW implementation, the BIT7 of RTC Index register(0x70) is
for NMI sources enable/disable but the BIT7 of 0x70 cannot be read
before writing. Software which doesn't want to change the NMI sources
enable/disable setting can write to the alias register 0x74, through
which only BIT0 ~ BIT6 of 0x70 is modified.
So two new PCDs are added so that platform can have the flexibility
to change the default RTC register addresses from 0x70/0x71 to
0x74/0x75.
With the new PCDs added, it can also support special HW that provides
RTC storage in a different register pairs.

Use FixedPCD's to set platform-specific values for RTC registers.
Specifically, the replaced macros are:
1) RTC_INIT_REGISTER_A
2) RTC_INIT_REGISTER_B
3) RTC_INIT_REGISTER_D

When a platform which doesn't support ACPI 1.0 (no XSDT) and FADT

GetCenturyRtcAddress() unconditionally deference Rsdp->RsdtAddress
but Rsdp->RsdtAddress is 0 in this case.

When ACPI table is installed before PcRtc driver runs,

The patch updates the Century value in CMOS location specified
by FADT.Century to avoid UEFI Win7 hang during booting.
Per the ACPI spec if the FADT.Century is zero, it's not needed
to store the century value in CMOS. But UEFI Win7 treats the
Century storage is optional only when FADT.Century is 0x80.
While Linux strictly follows the ACPI spec and treats Century
storage is optional when FADT.Century is 0.
So if a platform wants to support both UEFI Win7 and Linux,
it needs to report FADT.Century to a traditional value which
doesn't equal to 0 or 0x80 (0x32 mostly). And RTC driver is
enhanced to save the century value to the location specified
by FADT.Century.

The original driver cannot handle the case when system time runs from 1999/12/31 23:59:59
to 2000/1/1 0:0:0.
A simple test to set system time to 1999/12/31 23:59:59 can expose this bug.
The patch limits the driver to only support year in 100 range and decide the century value based
on the supporting range: Century either equals to PcdMinimalYear / 100 or equals to PcdMinimalYear / 100 + 1.
The patch passed the Y2K test.
However with year range [1998, 2097], when system time is 2097/12/31 23:59:59,
the next second system time will become 1998/1/1 0:0:0. I think it's a acceptable limitation.
