intel: Refactor reset manager driver
Refactor reset manager into intel common platform directory as it can be shared by both Stratix 10 and Agilex. Register address and field is now referred through macros. Signed-off-by: Hadi Asyrafi <muhammad.hadi.asyrafi.abdul.halim@intel.com> Change-Id: Id6d50f2a2f5a6bd8d6746b84602ac17ec7f6c07a
