This patch is important for the MicroSOM implementation due to the
following details -
1. VIH of the Atheros phy is 1.7V.
2. NVCC_ENET which is the power domain of the MDIO pad is driven by the
PHY's LDO (i.e. either 1.8v or 2.5v).
3. The MicroSOM implements an onbouard 1.6kohm pull up to 3.3v (R3000).
In the case the PHY's LDO was 1.8v then there would be only a 100mV
margin for the signal to be acknowledged as high (1.8v-1.7v).
Due to that setting the pad as an open drain will let the 1.6kohm pull
that signal high to 3.3 that assures enough margins to the PHY to be
acked as '1' logic.

Previous version had an extra 'fsl' which made the pins not match
any entry. The console message,
vf610-pinctrl 40048000.iomuxc: no fsl,pins property in node \
/soc/aips-bus@40000000/iomuxc@40048000/vf610-twr/esdhc1grp
is displayed without the fix. The prior version would generally
work as u-boot sets the pins properly for sdhc. This change allows
Linux sdhc use even if u-boot is built without sdhc support.

After the suspend routine running in OCRAM puts DDR into self-refresh,
it will access IOMUXC block to float DDR IO for power saving. A TLB
missing of IOMUXC base address may happen in this case, and triggers an
access to DDR, and thus hangs the system.
The failure is discovered by running suspend/resume on a Cubox-i board.
Though the issue is not Cubox-i specific, it can be hit the on the board
quite easily with the 3.15 or 3.16 kernel.
Fix the issue with a dummy access to IOMUXC block at the beginning of
suspend routine, so that the address translation can be filled into TLB
before DDR is put into self-refresh.

My earlier patch 1fc593feaf8e ("ARM: imx: build i.MX6 functions
only when needed") fixed a problem with building an i.MX5 kernel,
but now the problem has returned for the case where we allow
ARMv6K SMP builds in multiplatform. With CONFIG_CPU_V7 disabled,
but i.MX3 and SMP enabled, we get this build error:
arch/arm/mach-imx/built-in.o: In function `v7_secondary_startup':
:(.text+0x5124): undefined reference to `v7_invalidate_l1'
This puts the code inside of an "ifdef CONFIG_SOC_IMX6" to hopefully
do the right thing in all configurations.

Some Toshiba models (most notably Qosmios) come with an
incomplete backlight method where the AML code doesn't
check for write or read commands and always returns
HCI_SUCCESS and the actual brightness (and in some
cases the max brightness), thus allowing the backlight
interface to be registered without write support.
This patch changes the set_lcd_brightness function,
checking the returned values for values greater than
zero to avoid registering a broken backlight interface.

This patch removes the null test on block. block is initialized at the
beginning of the function to &wblock->gblock. Since wblock is
dereferenced prior to the null test, wblock must be a valid pointer,
and &wblock->gblock cannot be null.
The following Coccinelle script is used for detecting the change:
@r@

identifier g,y;
statement S1,S2;

*e = &f->g
