Linus Torvalds 3312db01db rpmsg updates for v5.18

The major part of the rpmsg changes for v5.18 relates to improvements in
 the rpmsg char driver, which now allow automatically attaching to rpmsg
 channels as well as initiating new communication channels from the Linux
 side.
 
 The SMD driver is moved to arch_initcall with the purpose of registering
 root clocks earlier during boot. Also in the SMD driver, a workaround
 for the resource power management (RPM) channel is introduced to resolve
 an issue where both the RPM and Linux side waits for the other to close
 the communication established by the bootloader - this unblocks support
 for clocks and regulators on some older Qualcomm platforms.
