This fixes various odd things that missed update together with cpm_uart
platform_device move. Unified resources names, restructurisation, etc.
Also, addressed issue with recent phys/virt translation rework. Being
cache-coherent, CPM2's do alloc_bootmem() for the console stuff, and it was
used to treat console buffer descriptor mapping 1:1 (as in CPM1 case),
which is definitely wrong.

Patch from Andrew Victor

The serial_core already manages the power state of the UARTs, and
therefore it shouldn't suspend a UART which was previously suspended.

This patch modifies serial_core only call the UART-specific
power-management function if the PM state is actually changing.

Patch from Sascha Hauer

This patch moves the i.MX uart resources and the gpio pin setup to the
board files. This allows the boards to decide how many internal uarts
are connected to the outside world and whether they use rts/cts or
not.

A number of small issues are fixed, and added the header file, missed from the
original series. With this, driver should be pretty stable as tested among
both platform-device-driven and "old way" boards. Also added missing GPL
statement , and updated year field on existing ones to reflect
code update.

SCC uart sends a break sequence each time it is stopped with the
CPM_CR_STOP_TX command. That means that each time an application closes the
serial device, a break is transmitted. To fix this, graceful tx stop is
issued for SCC.

x86 SMP breaks as a result of the previous change, we have no real
option other than to add locking to the 8250 console write function.
If an oops is in progress, try to acquire the lock.  If we fail to
do so, continue anyway.

A bug report from Gerd Hoffmann has highlighted that unconditionally
enabling the transmit interrupt at the end of console writes is very
bad.

In Gerd's case, it causes the test for buggy UARTs to give false
positives, incorrectly identifying ports as buggy when they are not.

Moreover, if we unconditionally enable the interrupt, and the port
is sharing it's interrupt with other ports, there is the very real
possibility that we'll cause an interrupt storm.  (Not all ports use
OUT2 as an interrupt mask.)

Hence, revert part of f91a3715db2bb44fcf08cec642e68f919b70f7f4 and
all of f5968b37b3ad35b682b574b578843a0361218aff until a better solution
can be found.
