There currently are multiple allocation API's in the LMB module. There
are a couple of API's for allocating memory(lmb_alloc() and
lmb_alloc_base()), and then there are two for requesting a reservation
for a particular memory region (lmb_reserve() and
lmb_alloc_addr()). Introduce a single API lmb_alloc_mem() which will
cater to all types of allocation requests and replace lmb_reserve()
and lmb_alloc_addr() with the new API.

Moreover, the lmb_reserve() API is pretty similar to the
lmb_alloc_addr() API, with the one difference being that the
lmb_reserve() API allows for reserving any address passed to it --
the address need not be part of the LMB memory map. The
lmb_alloc_addr() does check that the address being requested is
actually part of the LMB memory map.

There is no need to support reserving memory regions which are outside
the LMB memory map. Remove the lmb_reserve() API functionality and use
the functionality provided by lmb_alloc_addr() instead. The
lmb_alloc_addr() will check if the requested address is part of the
LMB memory map and return an error if not.

lmb_reserve() is just calling lmb_reserve_flags() with LMB_NONE.
There's not much we gain from this abstraction.
So let's remove the latter, add the flags argument to lmb_reserve()
and make the code a bit easier to follow.

The current LMB API's for allocating and reserving memory use a
per-caller based memory view. Memory allocated by a caller can then be
overwritten by another caller. Make these allocations and reservations
persistent using the alloced list data structure.

Two alloced lists are declared -- one for the available(free) memory,
and one for the used memory. Once full, the list can then be extended
at runtime.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

In a few places, the bootz command is used to handle a boot. We want
these to be done without needing CONFIG_CMDLINE, so add a new
bootz_run() function to handle this.

Rename the function to bootm_run_states() to better indicate ts

which this is now not.

Use the bootm_info struct to hold the information required by bootm.

Now that none of the functions called from do_bootm_states() needs an
argv[] list, change the arguments of do_bootm_states() as well. Take
care to use the same value for boot_progress even though it is a little
inconsistent.

For booti make sure it only uses argv[] and argc at the top of the
function, so we can eventually refactor to remove these parameters.

With bootm, some OSes need access to the arguments provided to the
command, so set these up in the bootm_info struct, for bootm only.
