omap: Serial: Define register access modes in LCR
Access to some registers depends on register access mode
Three different modes are available for OMAP (at least)
• Operational mode LCR_REG[7] = 0x0
• Configuration mode A LCR_REG[7] = 0x1 and LCR_REG[7:0]! = 0xBF
• Configuration mode B LCR_REG[7] = 0x1 and LCR_REG[7:0] = 0xBF
Define access modes and remove redefinitions and magic numbers
in serial drivers (and later in bluetooth driver).
