Merge branches 'next/cleanup' and 'next/fixes-non-critical' into next/cleanups-fixes

This is a merge of the cleanup and fixes-non-critical branches for the 4.7
merge window. It seems more appropriate to send a single pull request
for these than two separate ones, as both branches really contain both
fixes and cleanups.

* next/cleanup:
  ARM: debug: remove extraneous DEBUG_HI3716_UART option
  ARM: davinci: use IRQCHIP_DECLARE for cp_intc
  ARM: davinci: remove unused DA8XX_NUM_UARTS
  ARM: davinci: simplify call to of populate
  ARM: DaVinci USB: removed deprecated properties from MUSB config
  ARM: rockchip: Fix use of plain integer as NULL pointer
  ARM: realview: hide unused 'pmu_device' object
  soc: versatile: dynamically detect RealView HBI numbers

* next/fixes-non-critical:
  ARM: dts: exynos: Add interrupt line to MAX8997 PMIC on exynos4210-trats
  ARM: dts: exynos: Fix regulator name to avoid forbidden character on exynos4210-trats
  ARM: dts: exynos: Add MFC memory banks for Peach boards
  ARM: OMAP2+: n900 needs MMC slot names for legacy user space
  ARM: OMAP2+: Add more functions to pwm pdata for ir-rx51
  ARM: EXYNOS: Properly skip unitialized parent clock in power domain on
  ARM: OMAP2+: Simplify auxdata by using the generic match
  of/platform: Allow secondary compatible match in of_dev_lookup
