[PATCH 6.19 324/844] wifi: rtw89: pci: restore LDO setting after device resume

[Sasha Levin]

From: Dian-Syuan Yang <dian_syuan0116@xxxxxxxxxxx>

[ Upstream commit af1e82232b988f8fc6d635c60609765e49221a64 ]

The LDO (Low Dropout Regulator) setting is missing after suspend/resume
in some platforms, and it will cause card loss. Therefore, reconfigure
this setting to avoid it.
