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. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Simon Glass <sjg@chromium.org>
