ArmVirtPkg/ArmVirtQemu: enlarge initial flash mapping

The initial ID map used by ArmVirtQemu only covers 2 MiB of NOR flash,
while the NOOPT build can be up to 3 MiB in size, resulting in a crash
if the unmapped 1 MiB is accessed before the real page tables are up.

So increate the initial flash mapping to 4 MiB.
