mmc: core: Remove legacy 'enable-sdio-wakeup' DT property support

[PATCH] mmc: core: Remove legacy 'enable-sdio-wakeup' DT property support

Posted by Shawn Lin 6 days, 11 hours ago

The 'enable-sdio-wakeup' device tree property was marked as legacy and
superseded by the standard 'wakeup-source' property in commit 71a0151c5c82
("Documentation: devicetree: fix reference to legacy wakeup properties")
back in 2015.

Since it has been a decade and the migration to the standard property
has long been completed, remove this obsolete legacy support.
