The i.MX95-19x19 EVK board features a USB 2.0 Type-A port, with this
series primarily introducing USB 2.0 support. In the i.MX95 architecture,
the USB wake-up handling mechanism is integrated within the HSIO block
control module, utilizing a dedicated wake-up interrupt. Therefore, we
also implemented corresponding wake-up logic code to properly manage this
functionality.

For detailed changes can refer to patch commit log.

v4:
 - add blkctl NULL checking
 - warning if wakeup setting is missing for imx95
 - add Tb tag 

v3:
 - fix possible build break
 - remove usbmisc_imx95_init()
 - add Rb tag in some patches

v2:
 - apply some suggestions
 - improve wakeup interrupt handling
 - add Rb tag in some patches
