ArmVirtPkg: reduce preallocation of boot services data pages
Commit SVN r18503 ("MdeModulePkg DxeCore: Take the range in resource HOB for PHIT as higher priority") changed the GCD init logic to take the sum of the region sizes in gMemoryTypeInformation[] into account when estimating the minimal amount of memory needed to boot the system. Unfortunately, as an unintended side effect, this change results in boot failures of ArmVirtQemu when running with QEMU's default memory size of 128 MB. The reason is that the sum of the gMemoryTypeInformation region sizes plus the size of the inital PEI region exceeds 128 MB. Since we do not actually need to preallocate 20,000 pages' worth of BootServicesData memory, reduce this figure to the more reasonable 12,000.
