tegra kbc: Fixing android boot if key is kept press during boot.
Following changes are done:
- Created the new workqueue for the kbc scan process. On default workqueue,
the msleep() was not causing the schedule() to booting process.
- If there is no entry in fifo then wait for the next scan to complete before
re-reading the number of entries in the fifo. if there is no entry then rep
key released.
- Fixed timing calculation and size of the event entry array.
- Fixed the debaunce count calculation from debaunce time from odm.
Tested on whistler, with normal boot as well as with continous key pressed d
the entire boot time.
