soc: ti: k3-socinfo: Fix regmap leak on probe failure
Description
In the Linux kernel, the following vulnerability has been resolved: soc: ti: k3-socinfo: Fix regmap leak on probe failure The mmio regmap allocated during probe is never freed. Switch to using the device managed allocator so that the regmap is released on probe failures (e.g. probe deferral) and on driver unbind.
