Define new linker set, UART_FDT_CLASS_AND_DEVICE, for registering full
(class and device) FDT UART. Define second one, UART_FDT_CLASS, for UART
class only.
Move the uart_class definitions and fdt compat data into the individual
uart implementations, and export them using the new linker-set mechanism.

Return the actual baud rate programmed in the hardware rather than 115200.
This allows the "3wire" entry in /etc/ttys (with no speed specified) to work.
Use the FIFOs in the imx5/imx6 uart hardware instead of interrupting on
each byte sent or received.

The freescale imx uart driver works for the whole i.MX family, so rename
the header file to not have "5xx" in the name.
Flesh out imx_uart_init() so that we're not relying on u-boot to init
the hardware (meaning uarts other than the console will work).
Reword a comment block a bit.

Tell VM we now have ARM platforms with physically discontiguous memory.
Define the full 1024M of ram on the imx51 and imx53 boards.
Use a more professional uart device description.

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().
