[PATCH] common: make TLSF the default allocator

[PATCH] common: make TLSF the default allocator

[Ahmad Fatoum]

Going by the most used defconfigs (multi_*_defconfig), TLSF is the most
used allocator and it supports features absent in dlmalloc like
multiple pools (used on ARMv7-R) and has KASAN integration, so there's
even less reason to use dlmalloc nowadays.

In preparation for possible removal of dlmalloc in future, switch the
default away from dlmalloc.
