Subject: [PATCH] nrf/Makefile: Add _fs_size linker script override from make.

Add posibility to override linker script "_fs_size" from make by adding the
FS_SIZE parameter.  The syntax of value is linker script syntax.  For
example, the value of 131072 bytes can be written as 128K like this:
FS_SIZE=128K.

If not set, default value for "_fs_size" from linker script will be used.
