omap: hsmmc: assume cd gpio is active low

Switch the default CD GPIO polarity to active low.

The current hsmmc driver assumption that the CD GPIO is active high, but
in the real hardware, usually the opposite holds.
The usual SD card socket has a mechanical switch which is grounded as
soon as a card is inserted.
Of course there might be some board logic which inverts the signal, but
as far as current users are concerned, there is no such logic.

Current U-Boot users either not using the CD functionality, or have a
different way (e.g. external to SoC GPIO controller) for checking the
card presence.

This patch also brings the polarity assumption in line with the Linux
kernel and adds appropriate comments.

This patch also might spare issues once the TWL GPIO driver will be
converted to the DM.

omap3: cm-t35: extract the splash code from board

The splash screen loading code can be reused by other compulab boards.
For now extract it to a common location for further reuse.

This also switches the splash code dependency from CONFIG_LCD to
CONFIG_SPLASH_SCREEN as it should normally be.

In addition this patch fixes the accidental dependency of the
get_board_mem_timings() function on CONFIG_LCD, by just moving the
splash code and leaving the above function intact.

For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.

Also, it removes redundant "string" type in some Kconfig files.

The platform_data definitions are generally referenced from both
drivers and board files. That is why header files defining
platform_data sturectures are placed in "include" directory,
but our top level "include" directory is already too cluttered.

Let's collect platform_data definitions under the directory
"include/dm/platform_data" like Linux gathers ones around under
"include/linux/platform_data".

This commit moves two header files:

include/serial_mxc.h -> include/dm/platform_data/serial_mxc.h

each time a subsystem is initialized.

During board_init() muxes are setup and gpios are requested.
During subsystem init gpios are toggled.
