23:16 bits when they gets to SMC handler should be all zeros but be
inside SIP Service Calls range which is defined as 0x82000000-0x8200ffff
or 0xc2000000-0xc200ffff. That's why make sure that code won't handle
any SMCs in SIP range out of predefined range.
Also fix MASK values to check the same range for PM/IPI calls to make
sure that masking covers all required bits including 23:16. Bits 15:12
are used for different class of requests.
