allow LED initialization without STATUS_LED_BOOT

For current U-Boot to initialize status LEDs via status_led_init(), it
is required to have both CONFIG_STATUS_LED and STATUS_LED_BOOT defined.
This may be a particular concern with GPIO LEDs, where __led_init() is
required to correctly set up the GPIO (gpio_request and
gpio_direction_output). Without STATUS_LED_BOOT the initialization isn't
called, which could leave the user with a non-functional "led" command -
due to the fact that the LED routines in gpio_led.c use gpio_set_value()
just fine, but the GPIO never got set up properly in the first place.

I think having CONFIG_STATUS_LED is sufficient to justify a
corresponding call to status_led_init(), even with no STATUS_LED_BOOT
defined. To do so, common/board_r.c needs call that routine, so it now

This allows defining STATUS_LED_* values directly to GPIO numbers,
e.g.: #define STATUS_LED_GREEN 248 /* = PH24 */

To keep those optional, it's probably best to introduce an additional
configuration setting. I've chosen CONFIG_GPIO_LED_STUBS for that.

ARM: AM335x: mux: change mmc0 cd pinmux from mmc0_sdcd to gpio

Currently omap_hsmmc driver doesn't use sdcd pin to detect
whether the card is present or not. Instead the same pin is used
as GPIO to detect card presence. So change the pin mux mode from
mmc0_sdcd to gpio0_6.

drivers: gpio: omap: add support for parsing additional gpio parameters

With DM_GPIO, gpio parameters like ACTIVE_(LOW/HIGH) are to be
parsed in xlate gpio drivers-ops. Since xlate is not implemented
in omap_gpio driver, the driver considers all gpio to be
ACTIVE_HIGH which is the default case and fails to return actual
gpio status for ACTIVE_LOW gpios. So adding .xlate ops to
omap_gpio.
