Revert "Removing touchscreen insmod in the init to avoid conflict made by the script"

This reverts commit b423905b497a6a09e485c49c243a2ffd792dbb74.
Remove load_touchscreen.sh

Script is not necessary because the buyer code is written to sysfs
during stage1 init, and the touchscreen module is loaded during init.smdkc110.rc.
BT: Set bt_addr to sysfs used by stage1 init.
Remove bdaddr_read.sh

BT mac address is being written to sysfs by stage1 init.
Fix build conflicts with other devices.
Fixes for new keychar files.
Add additional keychar/keylayout for touchkeys (Fixes US Home button).

Devices with the capacitive home button were previously defaulting to the
Generic.kl, which has the 102 key mapped to MOVE_HOME.  Add keychar/keylayout
with the proper mapping of key 102 to HOME.
