RFC PATCH 1/1 of: of_reserved_mem: Increase limit on number of reserved regions

From: Patrick Daly <[email protected]>

Certain SoCs need to support a large amount of reserved memory regions. For example, Qualcomm's SM8150 SoC requires that 20 regions of memory be reserved for a variety of reasons (e.g. loading a peripheral subsystem's firmware image into a particular space).

When adding more reserved memory regions to cater to different usecases, the remaining number of reserved memory regions--12 to be exact--becomes too small. Thus, double the existing limit of reserved memory regions.
