Remove setting of fdt_high to ~0, which disables device tree relocation,
from the default environment. Doing so prevents U-Boot from correcting
problems such as having an unaligned device tree and leads to various
failure modes in the OS.

The definition of CFG_MXC_USB_PORTSC as (PORT_PTS_UTMI | PORT_PTS_PTW)
can be removed from mx5/mx6/mx7/mx8m board config files as it is the
default in drivers/usb/host/ehci-mx5.c and drivers/usb/host/ehci-mx6.c.

CFG_MXC_USB_FLAGS is only used for drivers/usb/host/ehci-mx5.c, so it
can be removed from all the imx6/imx7/imx8m board config files.

mx51evk.h is the only place CFG_MXC_USB_FLAGS is not set to 0.

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do
not easily transition to Kconfig. In many cases they likely should come
from the device tree instead. Move these out of CONFIG namespace and in
to CFG namespace.
