[PATCH] remoteproc: ingenic: Add module parameter 'auto_boot'

[Paul Cercueil]

Add a 'auto_boot' module parameter that instructs the remoteproc driver
whether or not it should auto-boot the remote processor, which will
default to "false", since the VPU in Ingenic SoCs does not really have
any predetermined function.
