Tom Rini f34a86c1ef led: Mark LED_STATUS as depending on LED being disabled 
The LED_STATUS functionality is part of the legacy LED framework. This
cannot be enabled at the same time as the new LED API is. Make the text
prompt be clear this is legacy and add a dependency on LED being
disabled.

config LED
bool "Enable LED support"
depends on DM
help
Many boards have LEDs which can be used to signal status or alerts.
U-Boot provides a uclass API to implement this feature. LED drivers
can provide access to board-specific LEDs. Use of the device tree
for configuration is encouraged.
config LED_BOOT
bool "Enable LED boot support"
help
Enable LED boot support.
LED boot is a specific LED assigned to signal boot operation status.
Defined in Device Tree /options/u-boot node. Refer here for the supported
options [1].
[1] dtschema/schemas/options/u-boot.yaml
config LED_ACTIVITY
bool "Enable LED activity support"
help
Enable LED activity support.
LED activity is a specific LED assigned to signal activity operation
like file trasnfer, flash write/erase...
Defined in Device Tree /options/u-boot node. Refer here for the supported
options [1].

config LED_BCM6328
bool "LED Support for BCM6328"
depends on LED && ARCH_BMIPS
help
This option enables support for LEDs connected to the BCM6328
LED HW controller accessed via MMIO registers.
HW blinking is supported and up to 24 LEDs can be controlled.
All LEDs can blink at the same time but the delay is shared, which
means that if one LED is set to blink at 100ms and then a different
LED is set to blink at 200ms, both will blink at 200ms.
config LED_BCM6358
bool "LED Support for BCM6358"
depends on LED && ARCH_BMIPS
help
This option enables support for LEDs connected to the BCM6358
LED HW controller accessed via MMIO registers.
HW has no blinking capabilities and up to 32 LEDs can be controlled.
config LED_BCM6753
bool "LED Support for BCM6753"
depends on LED && BCM6855
help
This option enables support for LEDs connected to the BCM6753
HW has blinking and fading capabilities and up to 32 LEDs can be controlled.
config LED_BCM6858
bool "LED Support for BCM6858"
depends on LED && (BCM6856 || BCM6858 || BCM63158)
help
This option enables support for LEDs connected to the BCM6858
HW has blinking capabilities and up to 32 LEDs can be controlled.
config LED_CORTINA
bool "LED Support for Cortina Access CAxxxx SoCs"
depends on LED && (CORTINA_PLATFORM)
help
This option enables support for LEDs connected to the Cortina
Access CAxxxx SOCs.
config LED_LP5562
bool "LED Support for LP5562"
depends on LED && DM_I2C
help
This option enables support for LEDs connected to the TI LP5562
4 channel I2C LED controller. Driver fully supports blink on the
B/G/R LEDs. White LED can blink, but re-uses the period from blue.
config LED_PWM
bool "LED PWM"
depends on LED && DM_PWM
help
Enable support for LEDs connected to PWM.
Linux compatible ofdata.
config LED_BLINK
bool "Support hardware LED blinking"
depends on LED
help
Some drivers can support automatic blinking of LEDs with a given
period, without needing timers or extra code to handle the timing.
This option enables support for this which adds slightly to the
code size.
config LED_SW_BLINK
bool "Support software LED blinking"
depends on LED
select CYCLIC
help
Turns on led blinking implemented in the software, useful when
the hardware doesn't support led blinking. Half of the period
led will be ON and the rest time it will be OFF. Standard
led commands can be used to configure blinking. Does nothing
if driver supports hardware blinking.
WARNING: Blinking may be inaccurate during execution of time
consuming commands (ex. flash reading). Also it completely
stops during OS booting.
config SPL_LED
bool "Enable LED support in SPL"
depends on SPL_DM
help
The LED subsystem adds a small amount of overhead to the image.
If this is acceptable and you have a need to use LEDs in SPL,
enable this option. You will need to enable device tree in SPL
for this to work.
config LED_GPIO
bool "LED support for GPIO-connected LEDs"
depends on LED && DM_GPIO
help
Enable support for LEDs which are connected to GPIO lines. These
GPIOs may be on the SoC or some other device which provides GPIOs.
The GPIO driver must used driver model. LEDs are configured using
the device tree.
config SPL_LED_GPIO
bool "LED support for GPIO-connected LEDs in SPL"
depends on SPL_LED && SPL_DM_GPIO
help
This option is an SPL-variant of the LED_GPIO option.
See the help of LED_GPIO for details.
