[PATCH 1/3] ArmVirtPkg/PrePi: Ensure timely execution of library constructors

["Ard Biesheuvel" <ardb@kernel.org>]

PrePi has a bare metal entry point, and so it is in charge of calling
the library constructors once the C runtime has been initialized
sufficiently.

However, we are now relying on a HOB to have been constructed by the
time the MMU code runs, and so the constructors should be run before
that.
