dm: serial: use Driver Model for UniPhier serial driver
This commit converts UniPhier on-chip serial driver to driver model.
Since UniPhier SoCs do not have Device Tree support, some board files
should be added under arch/arm/cpu/armv7/uniphier/ph1-*/ directories.
(Device Tree support for UniPhier platform is still under way.)
Now the base address and master clock frequency are passed from
platform data, so CONFIG_SYS_UNIPHIER_SERIAL_BASE* and
CONFIG_SYS_UNIPHIER_UART_CLK should be removed.
Tested on UniPhier PH1-LD4 ref board.
