Remove ArmEbPkg and replace with ArmRealViewEbPkg. Ported ArmRealViewEbPkg to have a PEI phase, and added place holder CPU PEIM to ArmPkg. This ArmRealViewEbPkg now boots from SEC, PEI, DXE, BDS, to EBL in the ARM RealView system emulator that comes with RealView Pro.

/** @file
Template for ArmEb DebugAgentLib.
For ARM we reserve FIQ for the Debug Agent Timer. We don't care about
laytency as we only really need the timer to run a few times a second
(how fast can some one type a ctrl-c?), but it works much better if
the interrupt we are using to break into the debugger is not being
used, and masked, by the system.

immediately before it rolls over is returned in EndValue. The 64-bit
frequency of the performance counter in Hz is always returned. If StartValue
is less than EndValue, then the performance counter counts up. If StartValue
is greater than EndValue, then the performance counter counts down. For
example, a 64-bit free running counter that counts up would have a StartValue
of 0 and an EndValue of 0xFFFFFFFFFFFFFFFF. A 24-bit free running counter
that counts down would have a StartValue of 0xFFFFFF and an EndValue of 0.
