PD#OTT-144
Problem:
after the dark screen, the adc button does not work
Solution:
The adc_keypad introduces earlysuspend for MID project:
after the LCD backlight disable, prevent the user from
pressing the key to open some applications and not complete standby.
Now check the adc button using the "system_freezable_wq" system queue,
which replaces the function of the code.So can remove it.

the following issues have been fixed :
1. didn't report any keys to userspace.
2. the push down of key is reported as push up.
3. no event is reported when press key for the first time.
adjust the key event value by changing the gpio flag for

1. the event value "0" is replaced to "1" when push down.
2. the event value "1" is replaced to "0" when push up.

PD#164774: kernel panic after mtk_cfg80211_set_power_mgmt
two possible overflow cases:
1. dev->debug_current + len == dev->debug_buffer_size
2. len > dev->debug_buffer_size
for the first case(currently triggered case)
the last byte of string pointed to by fmt, aka.'\0', will
overwrite the first byte of memory pointed to by header(in
function __register_sysctl_table), which is just the LSB of
ipv4_table[]'s base address. Leading to "Unable to handle
kernel paging request at virtual address xxxx" panic
for the second case
a bunch of memory pointed to by header(in function
__register_sysctl_table) will be overwritten

the sar adc driver has been moved from directory input/saradc
into directory iio/adc, and is refactored base on the standard
iio sub-system.
the iio sub-system provide two ways to access sar adc resources:
1. standard api for consumer driver
it can be found at the file "include/linux/iio/consumer.h".
2. sysfs interface for user space(X: 0-7)
- obtain 10-bit sample value:
cat sys/bus/iio/devices/iio:device0/in_voltage[X]_input
- obtain raw sample value(10-bit or 12-bit):
cat sys/bus/iio/devices/iio:device0/in_voltage[X]_raw
- obtain mean raw sample value:
cat sys/bus/iio/devices/iio:device0/in_voltage[X]_mean_raw
test pass on the gxl skt, axg skt, m200.
