Add clkctrl nodes for AM33xx SoC. These are going to be acting as
replacement for part of the existing clock data and the existing
clkctrl hooks under hwmod data.

This patch also removes any obsolete clock nodes, and reroutes all users
for these to use the new clkctrl clocks instead.

Though the keyboard driver for GPIO buttons(gpio-keys) will continue to
check for/support the legacy "gpio-key,wakeup" boolean property to
enable gpio buttons as wakeup source, "wakeup-source" is the new
standard binding.

This patch replaces the legacy "gpio-key,wakeup" with the unified
"wakeup-source" property in order to avoid any futher copy-paste
duplication.

Use the pinmux IOPAD macro to define the register absolute physical
address instead of the offset from the padconf base address. This
makes the DTS easier to read since matches the addresses listed in
the Technical Reference Manual.

Also, use the mux defines instead of magic numbers for the padconf
values when defining the pinctrl lines to make it more readable.

As per mmc device tree binding documentation card detect gpio has
to be active low signal. When a hardware is designed with active

In AM335x the card detect gpio is designed as active low gpio.
So correcting the dt card detect gpio definition.

While Sitara AM335x SoCs are very close to OMAP SoCs, the 32-line GPIO
controllers are numbered from 0 on AM335x and from 1 on OMAP. But when
the configuration for the TI WLAN controllers was converted from
platform data to device tree, this detail was overlooked, as 10 boards
were using OMAP with the WL12xx and WL18xx controllers, and only one
was based on AM335x.

This invalid configuration prevents the WL1271 module on the AM335x
EVM-SK from notifying interrupts to the SoC, and breaks the wlan driver.

The DTS must be corrected to use the correct GPIO controller.

Add the necessary nodes to enable the LCD controller and the
LCD panel that is attached to the Texas Instruments AM335x
EVMSK platform.  Also setup the necessary pin mux within the
DT file to drive the LCD connector and add the correct
pinmux settings for the lcd pins to be configured to when
the SoC goes into sleep state for the minimum power
consumption.

For the sleep mode LCD pin settings, MUX_MODE7 is chosen as
this corresponds to switching the pins into input GPIO's with
an internal pulldown.  Which has been determined to offer the
lowest power solution vs leaving the pins configured in LCD
mode.
