cti_flash.c: use __weak when requested for flash_(read|write){8,16,32,64}
For various reasons (design, errata) boards may need to implement their
own versions of these accessors. So in the case of
CONFIG_CFI_FLASH_USE_WEAK_ACCESSOR mark the functions as weak. In the
normal case mark them as static to allow for better optimization.

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.

dm: am335x: Remove serial options from CONFIG_SYS_EXTRA_OPTIONS
With these options in place it is not possible to change the serial port

In file included from include/linux/kconfig.h:4:0,
from <command-line>:0:
include/generated/autoconf.h:20:0: note: this is the location of the previous definition
#define CONFIG_CONS_INDEX 2

The default option seems to be 1 anyway, in board/ti/am335x/Kconfig.
Remove the options so that we can adjust the serial port if required.
