[Patch] BaseTools: Override Max size by build Option Pcd for HII type

[Yonghong Zhu <yonghong.zhu@intel.com>]

Current code will generate maxsize for HII type PCD when parser DSC
file, while this HII type PCD value maybe override in build command
per --pcd option, so the max size need re-calculate.
