Don't lock in the generic grab just to lock again in the specific grabs.

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.

Fix low-level uart drivers that set their fifo sizes in the softc too late.2013-04-01T00:44:20ZIan Leporeian@FreeBSD.org2013-04-01T00:44:20Zurn:sha1:4d7abca0576b034bbe0c4ac8d723ff15d36f4323
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.2008-03-03T18:20:17ZRafal Jaworowskiraj@FreeBSD.org2008-03-03T18:20:17Zurn:sha1:e1ef781113fba635a7fa4a979607261385971992
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.
