serial: 8250_uniphier: hardcode regshift to avoid unneeded memory read
For this driver, uart_port::regshift is always 2. Hardcode the
shift value instead of reading ->regshift to get an already known
value. (pointed out by Denys Vlasenko)
Furthermore, I am using register macros that are already shifted,
which will save code a bit.
