i2c: designware: Add comment to custom register value constants
DW_IC_COMP_VERSION register contains the ASCII representation of the
Synopsys component version. Here 0x3131312A == "111*" means version
1.11* required for DW_IC_SDA_HOLD register availability where '*' means
any letter starting from 'a'.
DW_IC_COMP_TYPE is constant and is derived from two ASCII letters "DW"
followed by a 16-bit unsigned number.
