ArmPlatformPkg: eliminate Juno gcc build warning

Browse Source 
When building without LTO, gcc incorrectly resolves the hazards for
'PciRegBase’ when inlining, leading to "may be used uninitialized"
warnings (and hence build failure with -Werror).
Eliminate this warning by explicitly initializing the variable to 0.
