Subject[PATCH v2 0/3] serial: 8250_dw: add fractional divisor support
For Synopsys DesignWare 8250 uart which version >= 4.00a, there's a
valid divisor latch fraction register. The fractional divisor width is
4bits ~ 6bits.

patch1 lets serial8250_get_divisor() get uart_port * as param
patch2 introduces necessary hooks to 8250 core.
patch3 implements the fractional divisor support for Synopsys DW 8250.

Since v1:
- add an extra patch to let serial8250_get_divisor() get uart_port *
as param
- take Andy's suggestions to "integrates hooks in the same way like
it's done for the rest of 8250 ones". Many thanks to Andy.

serial: 8250: introduce get_divisor() and set_divisor() hook
