Marek Vasut a3075db94d lmb: Reinstate access to memory above ram_top ...

Revert commit eb052cbb89 ("lmb: add and reserve memory above ram_top")
and commit 1a48b0be93 ("lmb: prohibit allocations above ram_top even from
same bank"). These are based on incorrect premise of the first commit, that
"U-Boot does not use memory above ram_top". While U-Boot itself indeed does
not and should not use memory above ram_top, user can perfectly well use
that memory from the U-Boot shell, for example to load content in there.

Currently, attempt to use that memory to load large image using TFTP ends
with "TFTP error: trying to overwrite reserved memory...". With this change
in place, the memory can be used again.

Fixes: eb052cbb89 ("lmb: add and reserve memory above ram_top")
Fixes: 1a48b0be93 ("lmb: prohibit allocations above ram_top even from same bank")
