[PATCH] drivers: base: Add prototype declaration in memory.c

[Rashika Kheria <rashika.kheria@gmail.com>]

Add the prototype declaration of function memory_block_size_bytes() in
memory.c.

This eliminates the following warning in memory.c:
drivers/base/memory.c:87:1: warning: no previous prototype for ‘memory_block_size_bytes’ [-Wmissing-prototypes]
