[PATCH 6.18 542/752] soc: ti: k3-socinfo: Fix regmap leak on probe failure

From: Johan Hovold <johan@kernel.org>

[ Upstream commit c933138d45176780fabbbe7da263e04d5b3e525d ]

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.

Fixes: a5caf03188e4 ("soc: ti: k3-socinfo: Do not use syscon helper to build regmap")
