GSI firmware.

dt-bindings: net: qcom,ipa: deprecate modem-init

GSI firmware for IPA must be loaded during initialization, either by
the AP or by the modem. The loader is currently specified based on
whether the Boolean modem-init property is present.

Instead, use a new property with an enumerated value to indicate
explicitly how GSI firmware gets loaded. With this in place, a
third approach can be added in an upcoming patch.

The new qcom,gsi-loader property has two defined values:
- self: The AP loads GSI firmware
- modem: The modem loads GSI firmware
The modem-init property must still be supported, but is now marked
deprecated.

Update the example so it represents the SC7180 SoC, and provide
examples for the qcom,gsi-loader, memory-region, and firmware-name
properties.

dt-bindings: net: qcom,ipa: restate a requirement

Either the AP or modem loads GSI firmware. If the modem-init
property is present, the modem loads it. Otherwise, the AP loads
it, and in that case the memory-region property must be defined.

Currently this requirement is expressed as one or the other of the
modem-init or the memory-region property being required. But it's
harmless for the memory-region to be present if the modem is loading
firmware (it'll just be ignored).

Restate the requirement so that the memory-region property is
required only if modem-init is not present.

Commit d8604b209e9b3 ("dt-bindings: net: qcom,ipa: add firmware-name

is more restrictive than necessary.

If the AP loads GSI firmware, the name of the firmware file to use
may optionally be provided via a "firmware-name" property. If the
*modem* loads GSI firmware, "firmware-name" doesn't need to be
supplied--but it's harmless to do so (it will simply be ignored).

Remove the unnecessary restriction, and allow "firware-name" to be
supplied even if it's not needed.

The easiest fix in most cases is to change the 'reg' property to for 1 cell
address and size. In some cases with child devices having 2 cells, that
doesn't make sense so a bus node is needed.
