ARM: SoC cleanups for v4.3

Browse Source 
A large cleanup branch this release, with a healthy 10k negative line delta.
 
 Most of this is removal of legacy (non-DT) support of shmobile
 platforms. There is also removal of two non-DT platforms on OMAP,
 and the plat-samsung directory is cleaned out by moving most of the
 previously shared-location-but-not-actually-shared files from there to
 the appropriate mach directories instead.
 
 There are other sets of changes in here as well:
 
  - Rob Herring removed use of set_irq_flags under all platforms and
    moved to genirq alternatives
  - A series of timer API conversions to set-state interface
  - ep93xx, nomadik and ux500 cleanups from Linus Walleij
  - __init annotation fixes from Nicolas Pitre
  + a bunch of other changes that all add up to a nice set of cleanups

/*************************************************************************
* Timer handling for EP93xx
*************************************************************************
* The ep93xx has four internal timers. Timers 1, 2 (both 16 bit) and
* 3 (32 bit) count down at 508 kHz, are self-reloading, and can generate
* an interrupt on underflow. Timer 4 (40 bit) counts down at 983.04 kHz,
* is free-running, and can't generate interrupts.
*
* The 508 kHz timers are ideal for use for the timer interrupt, as the
* most common values of HZ divide 508 kHz nicely. We pick one of the 16
* bit timers (timer 1) since we don't need more than 16 bits of reload
* value as long as HZ >= 8.
*
* The higher clock rate of timer 4 makes it a better choice than the
* other timers for use in gettimeoffset(), while the fact that it can't
* generate interrupts means we don't have to worry about not being able
* to use this timer for something else. We also use timer 4 for keeping
* track of lost jiffies.
