HV:CPU: Add 'U/UL' for unsigned const value
According to MISRA C:2012, suffix 'U/UL' shall be for unsigned const value, the member of enum variable should not be used to compare with integer variable. Add 'U/UL' for unsigned const value in the CPU module; Use Macro insteading of enum feature_word since the member of feature_word is used to compare with integer variable; Use hex number insteading of Macro in the assembly code. V1-->V2: Update the suffix of some constant value as 'UL' according to its'storage variable; Split MACRO updates used in the assembly code in other patch. Signed-off-by: Xiangyang Wu <xiangyang.wu@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>
