input: misc: hbtp_input: snapshot of driver from msm-4.9

Browse Source 
Driver snapshot from msm-4.9 to msm-next
0f798a0 input: misc: hbtp_input: allow read access to display_pwr sysfs
5532c00 input: misc: hbtp_input: Support for Region of Interest/sensors
61fbcdc6 input: misc: hbtp_input: Release mutex in error cases in sysfs cb
dc0b965 input: misc: hbtp_input: Add sysfs for suspend/resume
bafe727 input: misc: hbtp_input: snapshot of driver from msm-4.4
Use character device instead of miscellaneous device since
hbtp_input driver is an input device which can be classified
under character device. Misc devices are now deprecated.
