malloc_f: enable SYS_MALLOC_F by default if DM is on

Browse Source 
This option has a bool type, not hex.
Fix it and enable it if CONFIG_DM is on because Driver Model always

relocation.  CONFIG_SYS_MALLOC_F should be enabled to use malloc
memory before relocation.  As it is board-independent, handle it
globally.

Before relocation memory is very limited on many platforms. Still,
we can provide a small malloc() pool if needed. Driver model in
