ArmPkg: Fix Non-Boolean comparison in ArmGicEnableDistributor
According to edk2 coding standard specification, Non-Boolean comparisons must use a compare operator (==, !=, >, < >=, <=). See Section 5.7.2.1 at https://edk2-docs.gitbook.io/ edk-ii-c-coding-standards-specification/5_source_files/ 57_c_programming Therefore, fix the comparison in ArmGicEnableDistributor() Signed-off-by: Sami Mujawar <sami.mujawar@arm.com>
