Fixed corruption of LCM registers
Some registers where not set properly, or at the right time (thanks to Balaji
for his patch).
Weak locking could lead to corruption when using sysfs to switch state from
multiple threads or processes. The state transitions are now all atomic.
The driver attribute 'last_state' was used for same purpose of 'normal_state'.
Kept only 'normal_state' and used it in 'init_regs' instead of custom qvga
parameter.
This patch should fix bug #2235.
