soc: qualcomm: Add Shared Memory Manager driver The Shared Memory Manager driver implements an interface for allocating and accessing items in the memory area shared among all of the processors in a Qualcomm platform. Adapted from the Linux driver (4.17) Changes from the original Linux driver: * Removed HW spinlock mechanism, which is irrelevant in U-boot particualar use case, which is just reading from the smem. * Adapted from Linux driver model to U-Boot's.
