Commit c78dd25138d1 ("platform/x86: x86-android-tablets: Add Vexia EDU
ATLA 10 EC battery driver"), adds power_supply class registering to
the x86-android-tablets code.

Add "select POWER_SUPPLY" to the Kconfig entry to avoid these errors:

ERROR: modpost: "power_supply_get_drvdata" [drivers/platform/x86/x86-android-tablets/vexia_atla10_ec.ko] undefined!
ERROR: modpost: "power_supply_changed" [drivers/platform/x86/x86-android-tablets/vexia_atla10_ec.ko] undefined!
ERROR: modpost: "devm_power_supply_register" [drivers/platform/x86/x86-android-tablets/vexia_atla10_ec.ko] undefined!

When POWER_SUPPLY support is not enabled.

On the Vexia EDU ATLA 10 tablet, which ships with Android + a custom Linux
(guadalinex) using the custom Android kernel the I2C controllers are not
enumerated as ACPI devices as they typically are.

Instead they are enumerated as PCI devices which do not have ACPI firmware
nodes associated with them, so getting the i2c_adapter by the ACPI path of
its firmware node does not work.

Add support for getting the i2c_adapter by the devname() of its PCI parent
instead.

Fix spelling across comments (besides obvious grammar issues):
- spell words in full, e.g., 'img' --> 'image'
- refer to 'gpio-keys' consistently
- refer to acpi_power_off() clearly as to function
- make sure that the first line is only for the affected model(s)
- miscellaneous improvements

Since the x86-android-tablets now calls devm_led_classdev_register_ext()
it needs to select LEDS_CLASS as well as LEDS_CLASS' NEW_LEDS dependency.

Move the x86-android-tablets code into its own subdir, this is
a preparation patch for splitting the somewhat large file into
multiple smaller files.
