hw/arm/mps2-tz: Fix MPS2 SCC config register values

Browse Source 
Some of the config register values we were setting for the MPS2 SCC
weren't correct:
 * the SCC_AID bits [23:20] specify the FPGA build target board revision,
   and the SCC_CFG4 register specifies the actual board revision, so
   these should have matching values. Claim to be board revision C,
   consistently -- we had the revision in the wrong part of SCC_AID.
 * SCC_ID bits [15:4] should be 0x505, not decimal 505
