ArmPkg: allow HYP timer interrupt to be omitted
The DT binding for the ARM generic timer describes the secure,
non-secure, virtual and hypervisor timer interrupts, respectively.
However, under virtualization, only the virtual timer is usable, and
the device tree may omit the hypervisor timer interrupt. (Other timer
interrupts cannot be omitted simply due to the fact that the virtual
timer is listed third)

ArmPkg/TimerDxe: add workaround for KVM timer interrupt handling
KVM on ARM currently masks the timer interrupt on the timer side when
delivering an interrupt to the guest. This itself is a workaround for an
issue where the interrupt is reraised and trapped by the host as soon as
the guest is entered, resulting in the guest being starved.
Work around this by calling ArmGenericTimerEnable () after servicing each
interrupt. The virtual version of ArmGenericTimerCounterLib will then
make sure to unmask the interrupt again.

ArmPkg/TimerDxe: Read timer frequency from CPU
The PCD gArmTokenSpaceGuid.PcdArmArchTimerFreqInHz is used in the
SEC phase (if applicable) to write the platform's counter frequency
to the CNTFRQ system register, as this needs to be done by the highest
exception level implemented.
Under virtualization, we should be able to rely on the host to have
initialized this register to a sane value, as we run at EL1 and only
use the virtual timer, so the PcdArmArchTimerFreqInHz PCD has little
meaning here.
So in either case, by the time we enter the DXE phase, we can use the
CNTFRQ system register to read the frequency instead of looking at the
PCD.
