[PATCH 05/38] mmc: sunxi: use modern PM macros

From: Jisheng Zhang
Date: Thu Aug 14 2025 - 21:53:04 EST


Use the modern PM macros for the suspend and resume functions to be
automatically dropped by the compiler when CONFIG_PM or
CONFIG_PM_SLEEP are disabled, without having to use #ifdef guards.

This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.
