ARM: SoC fixes

A few fixes who have come in near or during the merge window:
 
  - Removal of a VLA usage in Marvell mpp platform code
  - Enable some IPMI options for ARM64 servers by default, helps testing
  - Enable PREEMPT on 32-bit ARMv7 defconfig
  - Minor fix for stm32 DT (removal of an unused DMA property)
  - Bugfix for TI OMAP1-based ams-delta (-EINVAL -> IRQ_NOTCONNECTED)
