Second round of Renesas ARM based SoC fixes for v3.11

Browse source 
* Lager board: do not annotate gpio_buttons as __initdata
   - This avoids accessing uninitialised memory if keys are pressed
     after kernel initialisation completes.
   - Bug introduced in gpio-keys were enabled in v3.11-rc1
 
 * Bock-W board: fix SDHI0 PFC settings
   - Allow detection of SD card
   - Bug introduced in SDHI support was added in v3.11-rc1
 
 * shdma: fixup sh_dmae_get_partial() calculation error
   - Bug introduced in 2.6.34-rc1.
 
 * armadillo800eva board: Don't request GPIO 166 in board code
   - Allow use of touchscreen
   - Bug introduced in v3.11-rc1
