input: i8042: Provide feature to disable keyboard before booting kernel

The BIOS leaves the keyboard enabled during boot time so that any
keystroke would interfere kernel driver initialization.

Add a way to disable the keyboard to make sure no scancode will be
generated during the boot time. Note that the keyboard will be
re-enabled again after the kernel driver is up.

This code can be called from the board functions.

input: Use finer grain udelays while waitng for the i8042 keyboard buffer to empty

On x86, the i8042 keyboard controller driver frequently waits for the keyboard
input buffer to be empty to make sure the controller has had a chance to
process the data it was given. The way the delay loop was structured, if the
controller hadn't cleared the corresponding status bit immediately, it would
wait 1ms before checking again. If the keyboard responded quickly but not
instantly, the driver would still wait a full 1ms when perhaps 1us would have
been sufficient. Because udelay is a busy wait anyway, this change decreases
the delay between checks to 1us.

Also, this change gets rid of a hardcoded 250ms delay.

the dir_entry structure, it can be noticed that the name[8] entry

since they're placed right next to each other by current compiler
behavior.

Depending on this is obviously wrong, thus fix this by correctly

function and adjust the function appropriately.

script scripts/kernel-doc and the scripts/docproc.c from Linux kernel and
implant it into U-Boot. This will allow smooth generation of kerneldoc

It was necessary to modify the DocBook/Makefile to work with U-Boot build

specific parts.

It was also necessary to replace use of variables like KERNEL_VERSION with
U_BOOT_VERSION, strings like Linux kernel with U-Boot Bootloader etc. so
the generated result actually matches.

Finally, it was necessary to adjust docproc.c, since the documentation in
U-Boot is located in doc/DocBook instead of Documentation/DocBook as is in
case of the Linux kernel.

Some parts of the DocBook Makefile are unused, but to allow easier sync with
Linux kernel, these parts are still left in. The targets enabled now are
"htmldocs" "pdfdocs" "psdocs" "xmldocs" and "cleandocs" to remove the results
