MDC setting depends on pclk input clocks which varies across SoC. This
driver is used by xilinx zynq and zynqmp SOC.
Input clock frequence on silicon is 125MHz where divider 64 put
frequency below 2.5MHz requires by spec (125/64=1.95).

Based on spec:
"MDC must not exceed 2.5 MHz (MDC is only active during MDIO read and
write operations)"
Zynq is running on 111MHz. Current setting is 32 which is 111/32=3.47
which is above of 2.5MHz.
Using 48 divider will give us correct setting according spec
(111/48=2.31).

Using set and clear macro is incorrect because it is not overwritting
origin mdc clock division setup.
For example origin setup is 8(0b001) and new setup is 64(0b100) which
means 0b101 is setup which is 96 divider.
Using writel to rewrite all setting like for 1000Mbit/s case.

MII is setup by default for all cases. The most of boards are using
RGMII but PHY drivers are not doing any specific setting that's why MII
setting was working fine. With TI DP83867 is necessary to setup
paramaters based on interface type.
Use one setting per board for it which is something what will be removed
when driver is moved to DM.

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:
#ifdef CONFIG_OF_CONTROL
# if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
# define OF_CONTROL 0
# else
# define OF_CONTROL 1
# endif
#else
# define OF_CONTROL 0
#endif
Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.
Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.
