Subject: [PATCH v4 0/4] soc: ti: Add module build support to the socinfo

In order for the TI K3 SoC info driver to be built as a module, the
following changes have been made:
- Converted memory allocations to devm and added the remove callback
- Added necessary code to build the driver as a module
- UDMA: Added deferred probe when soc_device_match() fails because the
socinfo driver is built as a module and hasn't probed yet
- MDIO: Same as the UDMA driver, return deferred probe if
soc_device_match() returns null

v2->v3:
dropped module conversion part of this series while other driver
dependencies on socinfo are worked out.
A dependency issue is introduced by changing subsys_initcall()
to module_platform_driver(). Some drivers using the socinfo information
probe before the socinfo driver itself and it makes their probe fail.

v3->v4:
reintegrated the module build support and added patches for udma and mdio
drivers to allow for deferred probe if socinfo hasn't probed yet.
