Fixed up conflicts in drivers/serial/apbuart.c with evil merge that

Thomas Gleixner 568389c257 serial: apbuart: Fixup apbuart_console_init()
commit 35c64e5d (drivers: serial: apbuart: Handle OF failures
gracefully) missed that the modified grlib_apbuart_configure()
function is called from apbuart_console_init() as well.

Fix the fallout.

Thomas Gleixner 35c64e5d13 drivers: serial: apbuart: Handle OF failures gracefully
The apbuart driver depends on OF and relies on everything being
available. So if it's probed on a platform which has OF support, but
no device tree is available it crashes. Triggered by the upcoming x86
OF support in randconfig testing.

Further it's inconsistent vs. the probing and exiting from the
of_match loop.

Make it robust and consistent:

 - check the availablility of OF nodes before dereferencing
 - return -ENODEV when the device tree lookup fails
 - return -ENODEV when no uart port configuration is found
 - return -ENODEV when invalid uart port configuration is found

Remove the enum_done check while at it. Driver init functions are only
called once. Remove the pointless vendor and device queries as well.

Grant Likely 2dc1158137 of/device: Replace struct of_device with struct platform_device
of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

Grant Likely 4018294b53 of: Remove duplicate fields from of_platform_driver
.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver.  This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.

This patch is a pretty mechanical change.  The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so
many files, but it should be pretty safe.

Grant Likely 61c7a080a5 of: Always use 'struct device.of_node' to get device node pointer.
The following structure elements duplicate the information in
'struct device.of_node' and so are being eliminated.  This patch
makes all readers of these elements use device.of_node instead.

(struct of_device *)->node
(struct dev_archdata *)->prom_node (sparc)
(struct dev_archdata *)->of_node (powerpc & microblaze)

This patch adds support for the APBUART serial port from Aeroflex
Gaisler's IP library GRLIB. It is currently used in all LEON3 designs
(SPARC V8) but can be used on other platforms as well (which support OF).
