On Peach Pit and Pi boards, the Exynos SoC XCLKOUT pin provides

Peach Pit and Pi boards have a WiFi module that is always powered
but needs toggling an enable pin and ungating a 32kHz reference
clock as part of their power sequencing.
Add a dev node for the SDIO slot and a MMC power sequence provider.

The Exynos5420 SoC has 3 sets of 8 pads used as data lines for the 3
MMC/SD/SDIO slots. These needs to be muxed as SD_n_DATA instead of a
GPIO or external interrupt to allow the MMC controller to communicate
with the attached cards or SDIO devices.
Which data lines needs to be muxed as SD_n_DATA depends on the bus
width used for data transfer:
* bus-width = <1> needs SD_n_DATA[0]
* bus-width = <4> needs SD_n_DATA[0-3]
* bus-width = <8> needs SD_n_DATA[0-7]
The Exynos5250-pinctrl.dtsi file that defines the groups of pins has
SD_n_DATA[0] muxed for both sdn_bus1 and sdn_bus4 so just one of them
needs to be included in the device node's pinctrl property.
But Exynos5420-pinctrl has a different definition and only includes
SD_n_DATA[1-3] for sdn_bus4. So for a bus-width = <4>, both sdn_bus1
and sdn_bus4 have to be in the dev pinctrl to mux all the needed pads.
It seems all Exynos5420 boards had just cargo cult the pinctrl lines
assuming that sdn_bus4 also included SD_n_DATA[0] and it only works
because the bootloader muxes the pads correctly. But that is not the
case for the devices not used by the bootloader such as WiFi modules.
Add sdn_bus1 too in the nodes pinctrl to not rely on the bootloader.

During CPU shutdown the exynos_cpu_power_down() is called after
disabling cache coherency and it uses LDREX and STREX instructions (by
calling of_machine_is_compatible() -> kobject_get() -> kref_get()).
The LDREX and STREX should not be used after disabling the cache
coherency so just use soc_is_exynos().

If we call groups_alloc() with invalid values then it's might lead to
memory corruption. For example, with a negative value then we might not
allocate enough for sizeof(struct group_info).
(We're doing this in the caller for consistency with other callers of
groups_alloc(). The other alternative might be to move the check out of
all the callers into groups_alloc().)
