Since commit ce412b79e7 ("drivers: net: phy: atheros: add separate
config for AR8031") Ethernet does not work on mx6sabreauto.
This commit correctly assigns ar8031_config() as the configuration
function for AR8031 in the same way as done in the Linux kernel.
However, on mx6sabreauto design we need some additional configurations,
such as enabling the 125 MHz AR8031 output and setting the TX clock
delay that need to be done in the board file.
This is the equivalent fix from commit 4b6035da48 ("mx6sabresd: Make
Ethernet functional again").

WEIM cannot be used when I2C3 is enabled due to pin conflict, so keep
WEIM disabled by default.
I2C3 controls GPIO I2C expander (USB host and OTG have VBUS controlled by
the GPIO I2C expander), magnetometer, accelerometer.
Not disabling WEIM in U-Boot causes I2C3 to behave badly when booting
a NXP 4.1 kernel, which leads to probe failure on several devices,
including the lack of USB:
imx_usb 2184000.usb: Can't register ci_hdrc platform device, err=-517
By keeping WEIM disabled in U-Boot these kernel issues are gone.

On the MX6Q the aclk_eim_slow_podf field is '1' after POR, while on the
MX6DQP it is '3'.
This makes the EIM clock to be only 66MHz on the mx6qp variant, instead of
132 MHz.
Instead of relying on the POR values for the CSMR1 register, make sure to
manually configure the clk_eim_slow_sel field as '00' so that EIM clock is
derived from AXI clock and the aclk_eim_slow_podf field as '1' so that EIM
clock can be AXI clock divided by 2.
This way a consistent EIM clock frequency is configured for all the mx6
variants.

On mx6 sabreauto board, there are two USB ports:

control is not implemented, which cause both USB port failed to work.
This patch fix the problem by adding the board support codes.
Since the power control uses the GPIO pin from port expander MAX7310,
the PCA953X driver is enabled for accessing the MAX7310.

Provide a public declaration of the board_spi_cs_gpio()

Signed-off-by: Eric Nelson <eric.nelson@boundarydevices.com>
MXC SPI driver has a feature whereas a GPIO line can be used to force CS high
across multiple transactions. This is set up by embedding the GPIO information
in the CS value:
cs = (cs | gpio << 8)
This merge of cs and gpio data into one value breaks the sf probe command:
if the use of gpio is required, invoking "sf probe <cs>" will not work, because
the CS argument doesn't have the GPIO information in it. Instead, the user must
use "sf probe <cs | gpio << 8>". For example, if bank 2 gpio 30 is used to force
cs high on cs 0, bus 0, then instead of typing "sf probe 0" the user now must
type "sf probe 15872".
This is inconsistent with the description of the sf probe command, and forces
the user to be aware of implementaiton details.
Fix this by introducing a new board function: board_spi_cs_gpio(), which will
accept a naked CS value, and provide the driver with the relevant GPIO, if one
is necessary.

PUE requires PKE to mean something, as do pull values with PUE, so do not

By the way, remove some unused pad control definitions.
There is no change of behavior.
Note that SPI_PAD_CTRL was defined by several boards with a pull value, but
without PKE or PUE, which means that no pull was actually enabled in the pad.
This might be a bug in those boards, but this patch does not change the
