So the memory for rx51_si4713_dev can be safely freed after init.
Also it references rx51_si4713_board_info which is __initdata_or_module.

memblock_steal tries to reserve physical memory during boot.
When the requested size is not aligned on the section size
then, the remaining memory available for lowmem becomes
unaligned on the section boundary. There is a issue with this,
which is discussed in the thread below.

https://lkml.org/lkml/2012/6/28/112

The final conclusion from the thread seems to
be align the memblock_steal calls on the SECTION boundary.
The issue comes out when LPAE is enabled, where the
section size is 2MB.

Boot tested this on OMAP5 evm with and without LPAE.

arch_is_coherent is problematic as it is a global symbol. This
doesn't work for multi-platform kernels or platforms which can support
per device coherent DMA.

This adds arm_coherent_dma_ops to be used for devices which connected
coherently (i.e. to the ACP port on Cortex-A9 or A15). The arm_dma_ops
are modified at boot when arch_is_coherent is true.
