[PATCH edk2-platforms 4/4] Vlv2TbltDevicePkg: Clean up the unused variables and function

["Gary Lin" <glin@suse.com>]

In PlatformBootOption.c:

* mContinueBoot and mBootMenuBoot were assigned as "!EnterSetup" before
  being used. However, EnterSetup is always "FALSE", so it's meaningless
  to keep those variables.

* mPxeBoot is defined but never used.

* DetectKeypressCallback() is never used. So we can remove it altogether
  with mHotKeypressed and HotKeyEvent.
