Subject: [PATCH 3/3] remoteproc: qcom: wcnss_iris: Fix module autoload

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/remoteproc/qcom_wcnss_iris.ko | grep alias
$

After this patch:

$ modinfo drivers/remoteproc/qcom_wcnss_iris.ko | grep alias
alias:          of:N*T*Cqcom,wcn3680C*
alias:          of:N*T*Cqcom,wcn3680
alias:          of:N*T*Cqcom,wcn3660C*
alias:          of:N*T*Cqcom,wcn3660
alias:          of:N*T*Cqcom,wcn3620C*
alias:          of:N*T*Cqcom,wcn3620
