Mako: Revert msm_fb: remove background invert alpha option for alpha drop pipe

This fixes the pie controls visual glitch when launching apps on the mako and
is required for this http://review.cyanogenmod.org/#/c/35314/ to work.

  When the blended background pipe has dropped alpha and it is going to
  be blended with foreground pipe on the next stage,
  MDP4_BLEND_BG_ALPHA_FG_CONST is taken. Foreground alpha constant is
  0xFF, so we need to use this alpha value to show background, instead
  of its inverted value.

Make sure PWMs are running in sync.

The 3 (red, green, blue) PWMs were sometimes running out of sync,
depending on the notification LED color flow and timing.

Make sure they are running in sync by
- adjusting the PWM atomically (that is, not adjust each one within its
  own worker task, where other tasks could get run inbetween)
- restarting the PWM if it was running before

Francisco is right, onlining all cores is a nice workaround for the real problem.
Onlining all cores using the driver's framework.
Some whitespace cleanup.

arm/crypto: Add optimized AES and SHA1 routines

Add assembler versions of AES and SHA1 for ARM platforms.  This has provided
up to a 50% improvement in IPsec/TCP throughout for tunnels using AES128/SHA1.
