arm-soc: bug fixes for 3.9-rc5 

After a quiet set of fixes for 3.9-rc4, a lot of people woke up and sent
 urgent fixes for 3.9. I pushed back on a number of them that got
 deferred to 3.10, but these are the ones that seemed important.
 
 Regression in 3.9:
 
 - Multiple regressions in OMAP2+ clock cleanup
 - SH-Mobile frame buffer bug fix that merged here because of maintainer MIA
 - ux500 prcmu changes broke DT booting
 - MMCI duplicated regulator setup on ux500
 - New ux500 clock driver broke ethernet on snowball
 - Local interrupt driver for mvebu broke ethernet
 - MVEBU GPIO driver did not get set up right on Orion DT
 - incorrect interrupt number on Orion crypto for DT
 
 Long-standing bugs, including candidates for stable:
 
 - Kirkwood MMC needs to disable invalid card detect pins
 - MV SDIO pinmux was wrong on Mirabox
 - GoFlex Net board file needs to set NAND chip delay
 - MSM timer restart race
 - ep93xx early debug code broke in 3.7
 - i.MX CPU hotplug race
 - Incorrect clock setup for OMAP1 USB
 - Workaround for bad clock setup by some old OMAP4 boot loaders
 - Static I/O mappings on cns3xxx since 3.2
