This enables the new or updates driver options for U8500
that got merged into v5.3-rc1:
- CMA, MCDE driver, LIMA driver and the Samsung S6D16D0 driver
enabled by default bringing up the new graphics support.
Include the LOGO so we can see when the graphics are live.
- We use the IIO hwmon bridge for reflecting temperature
in the system.
- Set MUSB to PIO mode as this is the one working most stable
for the time being.
- HWSPINLOCK needs to be set to get the hardware semaphore
driver to compile and link properly.

Remove the CONFIG_UEVENT_HELPER_PATH because:
1. It is disabled since commit 1be01d4a57 ("driver: base: Disable
CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was
made default to 'n',
2. It is not recommended (help message: "This should not be used today

3. Certain userland specifically requests it to be disabled (systemd

ux500 has seen continued conversion for platforms. Several platforms have
seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra

So, pretty much the same progression in the right direction as the last

Using 'select' in Kconfig is hard, a platform cannot just
enable a driver without also making sure that its subsystem
is there. Also, there is no actual code dependency between
the platform and the gpio leds driver.
Without this patch, building without LEDS_CLASS esults in:
drivers/built-in.o: In function `create_gpio_led.part.2':
governor_userspace.c:(.devinit.text+0x5a58): undefined reference to `led_classdev_register'
drivers/built-in.o: In function `gpio_led_remove':
governor_userspace.c:(.devexit.text+0x6b8): undefined reference to `led_classdev_unregister'
This reverts 8733f53c6 "ARM: ux500: Kconfig: Compile in leds-gpio
support for Snowball" that introduced the regression and did not
provide a helpful explanation.
In order to leave the GPIO LED code still present in normal
