  rpmsg: ctrl: Introduce new RPMSG_CREATE/RELEASE_DEV_IOCTL controls (2022-03-13 11:49:53 -0500)

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.
