Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.
Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

Introduce grab and ungrab upcalls. When the kernel desires to grab the console, it calls the grab functions. These functions should turn off the RX interrupts, and any others that interfere. This makes mountroot prompt work again. If there's more generalized need other than prompting, many of these routines should be expanded to do those new things.
Should have been part of r260889, but waasn't due to command line typo.

Fix low-level uart drivers that set their fifo sizes in the softc too late.
uart(4) allocates send and receiver buffers in attach() before it calls the low-level driver's attach routine. Many low-level drivers set the fifo sizes in their attach routine, which is too late. Other drivers set them in the probe() routine, so that they're available when uart(4) allocates buffers. This fixes the ones that were setting the values too late by moving the code to probe().

Support for Freescale QUad Integrated Communications Controller.
The QUICC engine is found on various Freescale parts including MPC85xx, and provides multiple generic time-division serial channel resources, which are in turn muxed/demuxed by the Serial Communications Controller (SCC).
Along with core QUICC/SCC functionality a uart(4)-compliant device driver is provided which allows for serial ports over QUICC/SCC.
