OMAP: process tput request made before PM init.

Because driver load order is uncertain, drivers could request bus
throughput constraints before the PM subsystem had initialized.  The
constraints would be recorded, but would have no effect on the actual
L3 clock.  This change suppresses attempts to set L3 scaling before PM
has initialized, and causes the PM subsystem to apply any pending bus
throughput constraints immediately after it has initialized itself.

 OMAP4: Enable wake-up feature for sys_nirq2

sys_nirq2 pin is used for twl6040 interrupt line which handles
events (like headset plug detection) that may need to wake-up the
device.

 omap4: hwmod_data: add clocks to ipu processor devices

The ipu processor hwmod devices (ipu_c0 & ipu_c1) are defined
primarily as pseudo-hwmod devices with only reset controls.
These share the same functional clock along with the ipu hwmod
device that is mainly used for controlling the MMU. This clock
name is added to these pseudo-hwmod devices, as it will improve
the robustness to any HW_AUTO settings performed within the
hwmod framework. There is no major effect on the clock framework
itself, as the clock enable & disable will simply be reference
counted and the functionality would be identical as before.

OMAP: I2C: Wait till functional part of the I2C controller completely becomes valid

Bus busy status bit is not effective when functional part of the I2C controller
is not valid, and bus busy detection in omap_i2c_wait_for_bb() will be skipped
sometimes. So we should wait till functional part of the I2C controller
completely becomes valid, after setting the I2Ci.I2C_CON[15] I2C_EN bit to 1.
For doing that we have to wait till RDONE bit of SYSS register reach "1".

For details see TRM, 23.1.4.3 HS I2C Software Reset.

ramdisk+AnyKernel2: major code cleanup
- fix insane whitespace and make formatting uniform in all Synapse files
- tighten up a lot of Synapse JSON and scripting
- add missing files to fix Synapse & suspend_trim support in AnyKernel2
- move tweaked KSM defaults from rc into bootscript
- correct permissions on some ramdisk files
- remove old zImage from AnyKernel2 dir, new ones can be added as needed
zimage for @aosp ;-)

radix-tree: introduce bit-optimized iterator
A series of radix tree cleanups, and usage of them in the core pagecache code. Micro-benchmark: lookup 14 slots (typical page-vector size) in radix-tree there earch <step> slot filled and tagged before/after - nsec per full scan through tree * Intel Sandy Bridge i7-2620M 4Mb L3 New code always faster * AMD Athlon 6000+ 2x1Mb L2, without L3 New code generally faster, Minor degradation (marked with "*") for huge sparse trees * i386 on Sandy Bridge New code faster for common cases: tagged and dense trees. Some degradations for non-tagged lookup on sparse trees. Ideally, there might help __ffs() analog for searching first non-zero long element in array, gcc sometimes cannot optimize this loop corretly.

Iterating divided into two phases: * lookup next chunk in radix-tree leaf node * iterating through slots in this chunk Main iterator function radix_tree_next_chunk() returns pointer to first slot, and stores in the struct radix_tree_iter index of next-to-last slot. For tagged-iterating it also constuct bitmask of tags for retunted chunk. All additional logic implemented as static-inline functions and macroses. Also adds radix_tree_find_next_bit() static-inline variant of find_next_bit() optimized for small constant size arrays, because find_next_bit() too heavy for searching in an array with one/two long elements.
