powerpc: Add support for early debugging via Serial 16550 console
Currently powerpc early debugging contains lot of platform specific options, but does not support standard UART / serial 16550 console.
Later legacy_serial.c code supports registering UART as early debug console from device tree but it is not early during booting, but rather later after machine description code finishes.
So for real early debugging via UART is current code unsuitable.
Add support for new early debugging option CONFIG_PPC_EARLY_DEBUG_16550 which enable Serial 16550 console on address defined by new option CONFIG_PPC_EARLY_DEBUG_16550_PHYSADDR and by stride by option CONFIG_PPC_EARLY_DEBUG_16550_STRIDE.
With this change it is possible to debug powerpc machine descriptor code. For example this early debugging code can print on serial console also "No suitable machine description found" error which is done before legacy_serial.c code.

powerpc/microwatt: Remove unused early debug code
The original microwatt submission[1] included some early debug code for using the Microwatt "potato" UART.
The series that was eventually merged switched to using a standard UART, and so doesn't need any special early debug handling. But some of the original code was merged accidentally under the non-existent CONFIG_PPC_EARLY_DEBUG_MICROWATT.
Drop the unused code.

powerpc/kernel: Add __init attribute to eligible functions
Some functions defined in `arch/powerpc/kernel` (and one in `arch/powerpc/ kexec`) are deserving of an `__init` macro attribute. These functions are only called by other initialization functions and therefore should inherit the attribute. Also, change function declarations in header files to include `__init`.

powerpc: Cleanup udbg_16550 and add support for LPC PIO-only UARTs
The udbg_16550 code, which we use for our early consoles and debug backends was fairly messy. Especially for the debug consoles, it would re-implement the "high level" getc/putc/poll functions for each access method. It also had code to configure the UART but only for the straight MMIO method.
This changes it to instead abstract at the register accessor level, and have the various functions and configuration routines use these.
The result is simpler and slightly smaller code, and free support for non-MMIO mapped PIO UARTs, which such as the ones that can be present on a POWER 8 LPC bus.

powerpc/udbg: Fix lost byte during console handover; change LFCR to CRLF
When the console is on a serial port to be driven by serial8250, a character can be lost from the end of the first line in the two-line sequence
serial8250.0: ttyS0 at MMIO 0xe0004500 (irq = 42) is a 16550A console handover: boot [udbg0] -> real [ttyS0]
This happens because udbg_puts or udbg_write stuff the last byte of the line into the Tx FIFO and return, whereupon the serial8250 initialization code immediately empties that FIFO. The fix: udbg_puts and udbg_write now wait for the Tx FIFO to clear before returning. This delays the system by one additional serial frame time for each line written by udbg, but the effect is not noticeable, a cumulative 17 milliseconds for 200 lines of early printk output at 115200 baud.
Also, the routines in udbg_16550.c now emit CRLF instead of LFCR. Linux makes a point of emitting CRLF because, when serial output is captured to a file, LFCR sequences can confuse text editors. See http://lkml.org/lkml/2006/2/4/50 for some history.
