[PATCH V2 0/5] Execute key notify function at TPL_CALLBACK

[Star Zeng <star.zeng@intel.com>]

Current implementation of keyboard driver executes key notify
function in TimerHandler at TPL_NOTIFY. The code change is to
make key notify function executed at TPL_CALLBACK to reduce
the time occupied at TPL_NOTIFY.

The code will signal KeyNotify process event if the key pressed
matches any key registered and insert the KeyData to the EFI Key
queue for notify, then the KeyNotify process handler will invoke
key notify functions at TPL_CALLBACK.

It can also address the problem raised at
https://lists.01.org/pipermail/edk2-devel/2016-December/005644.html

V2:
Based on the comments from Ruiyu, Ni,
add comments before calling Enqueue() to make the code more clear
and eliminate the call to IsQueueEmpty() in KeyNotifyProcessHandler().
