platform/x86: x86-android-tablets: Fix spelling in the comments

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
