espresso: set espresso and espressowifi variants to portrait mode

PS1: initial setup, hwrotation on init for espresso and espressowifi
     variants
PS2-5: proper Selinux rules for Android 5.1 and newer,
       move ramdisk to system/bin
PS6: also set accelerometer and geomagnetic position via sysfs and
     update Selinux rules
