Andy Shevchenko c1a67b48f6 serial: 8250_pci: replace switch-case by formula for Intel MID 
This patch replaces a switch-case by a formula using rational best
approximation that does necessary calculations for intel_mid_set_termios().

Below is a list of the calculations done for all defined baud rates. Each line
in a format: 1) nominator, 2) denominator, 3) prescaler, 4) Fuart, 5) port UART
clock, 6) list of baud rates with DLAB values.
