The original commit had typos for two of the memory client ids. Fix them
to reference the correct bindings.

Since the related binding is being added, use that for the client ids
instead of hardcoded magic numbers.

<title>memory: tegra: Add Tegra264 MC and EMC support</title>

<id>2401dc4dcdd02920faa9a8c4384f1503a15e779a</id>
<content type='text'>
Add support to enable Memory Controller (MC) and External Memory
Controller (EMC) drivers for Tegra264. The nodes for MC and EMC are
mostly the same as Tegra234 but differ in number of channels and
interrupt numbers.

The patch also adds the bandwidth manager definitions required for
Tegra264 and uses them to populate the memory client table. All of
these are needed to properly enable memory interconnect (ICC) support.

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree
over and remove the historical wrapper inlines.

Conversion was done with coccinelle plus manual fixups where necessary.

platform_get_irq() already prints error message, so duplicating it is
redundant.  The message about "need of updating DT" makes no sense,
because this code was there since beginning.

As of_find_node_by_name() release the reference of the argument device
node, tegra_emc_find_node_by_ram_code() releases some device nodes while
still in use, resulting in possible UAFs. According to the bindings and
the in-tree DTS files, the "emc-tables" node is always device's child
node with the property "nvidia,use-ram-code", and the "lpddr2" node is a
child of the "emc-tables" node. Thus utilize the
for_each_child_of_node() macro and of_get_child_by_name() instead of
of_find_node_by_name() to simplify the code.

This bug was found by an experimental verification tool that I am
developing.

<title>Get rid of 'remove_new' relic from platform driver struct</title>

<content type='text'>
The continual trickle of small conversion patches is grating on me, and
is really not helping.  Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:

  /*
   * .remove_new() is a relic from a prototype conversion of .remove().
   * New drivers are supposed to implement .remove(). Once all drivers are
   * converted to not use .remove_new any more, it will be dropped.
   */

This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.

I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.

Then I just removed the old (sic) .remove_new member function, and this
is the end result.  No more unnecessary conversion noise.
