Add missing #inclusions of <linux/irq.h> to a whole bunch of files that should
really include it. Note that this can replace #inclusions of <asm/irq.h>.
This is required for the patch to sort out irqflags handling function naming to
compile on MIPS.
The problem is that these files require access to things like setup_irq() -
which isn't available by #including <linux/interrupt.h>

The IOC interrupt status register on RBTX49XX only have 8 bits. Use
8-bit version of __fls() to optimize interrupt handlers.

* Random cleanups spotted by checkpatch script.
* Do not initialize panic_timeout. "panic=" kernel parameter can be used.
* Do not add "ip=any" or "ip=bootp". This options is not board specific.
* Do not add "root=/dev/nfs". This is default on CONFIG_ROOT_NFS.
* Kill unused error checking.
* Fix IRQ comment to match current code.
* Kill some unneeded includes
* ST0_ERL is already cleared in generic code.
* conswitchp is initialized generic code.
* __init is not needed in prototype.

SYS_SUPPORTS_64BIT_KERNEL is enabled for RBTX4927/RBTX4938, but
actually it was broken for long time (or from the beginning). Now it
should work.

Make single kernel can be used on RBTX4927/37/38. Also make
some SoC-specific code independent from board-specific code.

Split out PCIC dependent code and SoC dependent code from board dependent
code. Now TX4927 PCIC code is independent from TX4927/TX4938 SoC code.
Also fix some build problems on CONFIG_PCI=n.
As a bonus, "FPCIB0 Backplane Support" is available for all TX39/TX49 boards
and PCI66 support is available for all TX49 boards.

Move arch/mips/{jmr3927,tx4927,tx4938} into arch/mips/txx9/ tree.
This will help more code sharing and maintainance.
